[PATCH openEuler-1.0-LTS] ath5k: fix OOB in ath5k_eeprom_read_pcal_info_5111
by Peng Zhang 27 Mar '25

27 Mar '25

From: Zekun Shen <bruceshenzk(a)gmail.com> stable inclusion from stable-v4.19.238 commit 25efc5d03455c3839249bc77fce5e29ecb54677e category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP5YP CVE: CVE-2021-47633 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ------------------------------------------- [ Upstream commit 564d4eceb97eaf381dd6ef6470b06377bb50c95a ] The bug was found during fuzzing. Stacktrace locates it in ath5k_eeprom_convert_pcal_info_5111. When none of the curve is selected in the loop, idx can go up to AR5K_EEPROM_N_PD_CURVES. The line makes pd out of bound. pd = &chinfo[pier].pd_curves[idx]; There are many OOB writes using pd later in the code. So I added a sanity check for idx. Checks for other loops involving AR5K_EEPROM_N_PD_CURVES are not needed as the loop index is not used outside the loops. The patch is NOT tested with real device. The following is the fuzzing report BUG: KASAN: slab-out-of-bounds in ath5k_eeprom_read_pcal_info_5111+0x126a/0x1390 [ath5k] Write of size 1 at addr ffff8880174a4d60 by task modprobe/214 CPU: 0 PID: 214 Comm: modprobe Not tainted 5.6.0 #1 Call Trace: dump_stack+0x76/0xa0 print_address_description.constprop.0+0x16/0x200 ? ath5k_eeprom_read_pcal_info_5111+0x126a/0x1390 [ath5k] ? ath5k_eeprom_read_pcal_info_5111+0x126a/0x1390 [ath5k] __kasan_report.cold+0x37/0x7c ? ath5k_eeprom_read_pcal_info_5111+0x126a/0x1390 [ath5k] kasan_report+0xe/0x20 ath5k_eeprom_read_pcal_info_5111+0x126a/0x1390 [ath5k] ? apic_timer_interrupt+0xa/0x20 ? ath5k_eeprom_init_11a_pcal_freq+0xbc0/0xbc0 [ath5k] ? ath5k_pci_eeprom_read+0x228/0x3c0 [ath5k] ath5k_eeprom_init+0x2513/0x6290 [ath5k] ? ath5k_eeprom_init_11a_pcal_freq+0xbc0/0xbc0 [ath5k] ? usleep_range+0xb8/0x100 ? apic_timer_interrupt+0xa/0x20 ? ath5k_eeprom_read_pcal_info_2413+0x2f20/0x2f20 [ath5k] ath5k_hw_init+0xb60/0x1970 [ath5k] ath5k_init_ah+0x6fe/0x2530 [ath5k] ? kasprintf+0xa6/0xe0 ? ath5k_stop+0x140/0x140 [ath5k] ? _dev_notice+0xf6/0xf6 ? apic_timer_interrupt+0xa/0x20 ath5k_pci_probe.cold+0x29a/0x3d6 [ath5k] ? ath5k_pci_eeprom_read+0x3c0/0x3c0 [ath5k] ? mutex_lock+0x89/0xd0 ? ath5k_pci_eeprom_read+0x3c0/0x3c0 [ath5k] local_pci_probe+0xd3/0x160 pci_device_probe+0x23f/0x3e0 ? pci_device_remove+0x280/0x280 ? pci_device_remove+0x280/0x280 really_probe+0x209/0x5d0 Reported-by: Brendan Dolan-Gavitt <brendandg(a)nyu.edu> Signed-off-by: Zekun Shen <bruceshenzk(a)gmail.com> Signed-off-by: Kalle Valo <quic_kvalo(a)quicinc.com> Link: https://lore.kernel.org/r/YckvDdj3mtCkDRIt@a-10-27-26-18.dynapool.vpn.nyu.e… Signed-off-by: Sasha Levin <sashal(a)kernel.org> Signed-off-by: ZhangPeng <zhangpeng362(a)huawei.com> --- drivers/net/wireless/ath/ath5k/eeprom.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/drivers/net/wireless/ath/ath5k/eeprom.c b/drivers/net/wireless/ath/ath5k/eeprom.c index 94d34ee02265..01163b333945 100644 --- a/drivers/net/wireless/ath/ath5k/eeprom.c +++ b/drivers/net/wireless/ath/ath5k/eeprom.c @@ -746,6 +746,9 @@ ath5k_eeprom_convert_pcal_info_5111(struct ath5k_hw *ah, int mode, } } + if (idx == AR5K_EEPROM_N_PD_CURVES) + goto err_out; + ee->ee_pd_gains[mode] = 1; pd = &chinfo[pier].pd_curves[idx]; -- 2.25.1

[PATCH OLK-6.6] ASoC: soc-pcm: don't use soc_pcm_ret() on .prepare callback
by Qi Xi 27 Mar '25

27 Mar '25

From: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> mainline inclusion from mainline-v6.14-rc1 commit 301c26a018acb94dd537a4418cefa0f654500c6f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBRED3 CVE: CVE-2024-58077 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- commit 1f5664351410 ("ASoC: lower "no backend DAIs enabled for ... Port" log severity") ignores -EINVAL error message on common soc_pcm_ret(). It is used from many functions, ignoring -EINVAL is over-kill. The reason why -EINVAL was ignored was it really should only be used upon invalid parameters coming from userspace and in that case we don't want to log an error since we do not want to give userspace a way to do a denial-of-service attack on the syslog / diskspace. So don't use soc_pcm_ret() on .prepare callback is better idea.

[PATCH openEuler-1.0-LTS] media: pvrusb2: fix array-index-out-of-bounds in pvr2_i2c_core_init
by Gu Bowen 26 Mar '25

26 Mar '25

From: Pavel Skripkin <paskripkin(a)gmail.com> stable inclusion from stable-v4.19.247 commit a3660e06675bccec4bf149c7229ea1d491ba10d7 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP6VC CVE: CVE-2022-49478 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 471bec68457aaf981add77b4f590d65dd7da1059 ] Syzbot reported that -1 is used as array index. The problem was in missing validation check. hdw->unit_number is initialized with -1 and then if init table walk fails this value remains unchanged. Since code blindly uses this member for array indexing adding sanity check is the easiest fix for that. hdw->workpoll initialization moved upper to prevent warning in __flush_work.

[PATCH openEuler-1.0-LTS] media: uvcvideo: Remove dangling pointers
by Zhao Yipeng 26 Mar '25

26 Mar '25

From: Ricardo Ribalda <ribalda(a)chromium.org> mainline inclusion from mainline-v6.14-rc1 commit 221cd51efe4565501a3dbf04cc011b537dcce7fb category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPC8W CVE: CVE-2024-58002 Reference: https://web.git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/comm… -------------------------------- When an async control is written, we copy a pointer to the file handle that started the operation. That pointer will be used when the device is done. Which could be anytime in the future. If the user closes that file descriptor, its structure will be freed, and there will be one dangling pointer per pending async control, that the driver will try to use. Clean all the dangling pointers during release(). To avoid adding a performance penalty in the most common case (no async operation), a counter has been introduced with some logic to make sure that it is properly handled.

From: Ryusuke Konishi <konishi.ryusuke(a)gmail.com> mainline inclusion from mainline-v6.14-rc1 commit ca76bb226bf47ff04c782cacbd299f12ddee1ec1 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPBK0 CVE: CVE-2025-21722 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ---------------------- Patch series "nilfs2: protect busy buffer heads from being force-cleared". This series fixes the buffer head state inconsistency issues reported by syzbot that occurs when the filesystem is corrupted and falls back to read-only, and the associated buffer head use-after-free issue. This patch (of 2): Syzbot has reported that after nilfs2 detects filesystem corruption and falls back to read-only, inconsistencies in the buffer state may occur.

[PATCH OLK-6.6] ata: libata-sff: Ensure that we cannot write outside the allocated buffer
by Zheng Qixing 26 Mar '25

26 Mar '25

From: Niklas Cassel <cassel(a)kernel.org> stable inclusion from stable-v6.6.78 commit d5e6e3000309359eae2a17117aa6e3c44897bf6c category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPC5G CVE: CVE-2025-21738 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ------------------ commit 6e74e53b34b6dec5a50e1404e2680852ec6768d2 upstream. reveliofuzzing reported that a SCSI_IOCTL_SEND_COMMAND ioctl with out_len set to 0xd42, SCSI command set to ATA_16 PASS-THROUGH, ATA command set to ATA_NOP, and protocol set to ATA_PROT_PIO, can cause ata_pio_sector() to write outside the allocated buffer, overwriting random memory. While a ATA device is supposed to abort a ATA_NOP command, there does seem to be a bug either in libata-sff or QEMU, where either this status is not set, or the status is cleared before read by ata_sff_hsm_move(). Anyway, that is most likely a separate bug. Looking at __atapi_pio_bytes(), it already has a safety check to ensure that __atapi_pio_bytes() cannot write outside the allocated buffer.

[PATCH OLK-6.6] block: don't revert iter for -EIOCBQUEUED
by Zheng Qixing 26 Mar '25

26 Mar '25

From: Jens Axboe <axboe(a)kernel.dk> stable inclusion from stable-v6.6.78 commit 84671b0630ccb46ae9f1f99a45c7d63ffcd6a474 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBRECT CVE: CVE-2025-21832 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ------------------ commit b13ee668e8280ca5b07f8ce2846b9957a8a10853 upstream. blkdev_read_iter() has a few odd checks, like gating the position and count adjustment on whether or not the result is bigger-than-or-equal to zero (where bigger than makes more sense), and not checking the return value of blkdev_direct_IO() before doing an iov_iter_revert(). The latter can lead to attempting to revert with a negative value, which when passed to iov_iter_revert() as an unsigned value will lead to throwing a WARN_ON() because unroll is bigger than MAX_RW_COUNT. Be sane and don't revert for -EIOCBQUEUED, like what is done in other spots.

[PATCH openEuler-1.0-LTS] net_sched: sch_sfq: don't allow 1 packet limit
by Wang Liang 26 Mar '25

26 Mar '25

From: Octavian Purdila <tavip(a)google.com> mainline inclusion from mainline-v6.14-rc1 commit 10685681bafce6febb39770f3387621bf5d67d0b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBVH45 CVE: CVE-2024-57996 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The current implementation does not work correctly with a limit of 1. iproute2 actually checks for this and this patch adds the check in kernel as well.

TBF is out of tokens so it schedules itself for later. * the second packet is sent and TBF tries to queues it to SFQ. qdisc qlen is now 2 and because the SFQ limit is 1 the packet is dropped by SFQ. At this point qlen is 1, and all of the SFQ slots are empty, however q->tail is not NULL. At this point, assuming no more packets are queued, when sch_dequeue runs again it will decrement the qlen for the current empty slot causing an underflow and the subsequent out of bounds access.

[PATCH openEuler-1.0-LTS] ALSA: oss: Fix PCM OSS buffer allocation overflow
by Jinjiang Tu 25 Mar '25

25 Mar '25

From: Takashi Iwai <tiwai(a)suse.de> stable inclusion from stable-v4.19.237 commit a63af1baf0a5e11827db60e3127f87e437cab6e5 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP1SP CVE: CVE-2022-49292 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit efb6402c3c4a7c26d97c92d70186424097b6e366 upstream. We've got syzbot reports hitting INT_MAX overflow at vmalloc() allocation that is called from snd_pcm_plug_alloc(). Although we apply the restrictions to input parameters, it's based only on the hw_params of the underlying PCM device. Since the PCM OSS layer allocates a temporary buffer for the data conversion, the size may become unexpectedly large when more channels or higher rates is given; in the reported case, it went over INT_MAX, hence it hits WARN_ON(). This patch is an attempt to avoid such an overflow and an allocation for too large buffers. First off, it adds the limit of 1MB as the upper bound for period bytes. This must be large enough for all use cases, and we really don't want to handle a larger temporary buffer than this size. The size check is performed at two places, where the original period bytes is calculated and where the plugin buffer size is calculated. In addition, the driver uses array_size() and array3_size() for multiplications to catch overflows for the converted period size and buffer bytes.

[PATCH openEuler-1.0-LTS] macsec: fix UAF bug for real_dev
by Wang Liang 25 Mar '25

25 Mar '25

From: Ziyang Xuan <william.xuanziyang(a)huawei.com> mainline inclusion from mainline-v5.19-rc1 commit 196a888ca6571deb344468e1d7138e3273206335 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP2L3 CVE: CVE-2022-49390 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Create a new macsec device but not get reference to real_dev. That can not ensure that real_dev is freed after macsec. That will trigger the UAF bug for real_dev as following: ================================================================== BUG: KASAN: use-after-free in macsec_get_iflink+0x5f/0x70 drivers/net/macsec.c:3662 Call Trace: ... macsec_get_iflink+0x5f/0x70 drivers/net/macsec.c:3662 dev_get_iflink+0x73/0xe0 net/core/dev.c:637 default_operstate net/core/link_watch.c:42 [inline] rfc2863_policy+0x233/0x2d0 net/core/link_watch.c:54 linkwatch_do_dev+0x2a/0x150 net/core/link_watch.c:161 Allocated by task 22209: ... alloc_netdev_mqs+0x98/0x1100 net/core/dev.c:10549 rtnl_create_link+0x9d7/0xc00 net/core/rtnetlink.c:3235 veth_newlink+0x20e/0xa90 drivers/net/veth.c:1748 Freed by task 8: ... kfree+0xd6/0x4d0 mm/slub.c:4552 kvfree+0x42/0x50 mm/util.c:615 device_release+0x9f/0x240 drivers/base/core.c:2229 kobject_cleanup lib/kobject.c:673 [inline] kobject_release lib/kobject.c:704 [inline] kref_put include/linux/kref.h:65 [inline] kobject_put+0x1c8/0x540 lib/kobject.c:721 netdev_run_todo+0x72e/0x10b0 net/core/dev.c:10327 After commit faab39f63c1f ("net: allow out-of-order netdev unregistration") and commit e5f80fcf869a ("ipv6: give an IPv6 dev to blackhole_netdev"), we can add dev_hold_track() in macsec_dev_init() and dev_put_track() in macsec_free_netdev() to fix the problem.

[PATCH OLK-6.6] btrfs: do proper folio cleanup when cow_file_range() failed

25 Mar '25

From: Qu Wenruo <wqu(a)suse.com> stable inclusion from stable-v6.13.2 commit 692cf71173bb41395c855acbbbe197d3aedfa5d4 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPBJV CVE: CVE-2024-57976 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 06f364284794f149d2abc167c11d556cf20c954b upstream. [BUG] When testing with COW fixup marked as BUG_ON() (this is involved with the new pin_user_pages*() change, which should not result new out-of-band dirty pages), I hit a crash triggered by the BUG_ON() from hitting COW fixup path. This BUG_ON() happens just after a failed btrfs_run_delalloc_range(): BTRFS error (device dm-2): failed to run delalloc range, root 348 ino 405 folio 65536 submit_bitmap 6-15 start 90112 len 106496: -28 ------------[ cut here ]------------ kernel BUG at fs/btrfs/extent_io.c:1444!

Although the -ENOSPC is already a bug related to our space reservation code, let's just focus on the error handling. For example, we have the following dirty range [0, 64K) of an inode, with 4K sector size and 4K page size: 0 16K 32K 48K 64K |///////////////////////////////////////| |#######################################| Where |///| means page are still dirty, and |###| means the extent io tree has EXTENT_DELALLOC flag. - Enter extent_writepage() for page 0 - Enter btrfs_run_delalloc_range() for range [0, 64K) - Enter cow_file_range() for range [0, 64K) - Function btrfs_reserve_extent() only reserved one 16K extent So we created extent map and ordered extent for range [0, 16K) 0 16K 32K 48K 64K |////////|//////////////////////////////| |<- OE ->|##############################| And range [0, 16K) has its delalloc flag cleared. But since we haven't yet submit any bio, involved 4 pages are still dirty. - Function btrfs_reserve_extent() returns with -ENOSPC Now we have to run error cleanup, which will clear all EXTENT_DELALLOC* flags and clear the dirty flags for the remaining ranges: 0 16K 32K 48K 64K |////////| | | | | Note that range [0, 16K) still has its pages dirty. - Some time later, writeback is triggered again for the range [0, 16K) since the page range still has dirty flags. - btrfs_run_delalloc_range() will do nothing because there is no EXTENT_DELALLOC flag. - extent_writepage_io() finds page 0 has no ordered flag Which falls into the COW fixup path, triggering the BUG_ON(). Unfortunately this error handling bug dates back to the introduction of btrfs. Thankfully with the abuse of COW fixup, at least it won't crash the kernel. [FIX] Instead of immediately unlocking the extent and folios, we keep the extent and folios locked until either erroring out or the whole delalloc range finished. When the whole delalloc range finished without error, we just unlock the whole range with PAGE_SET_ORDERED (and PAGE_UNLOCK for !keep_locked cases), with EXTENT_DELALLOC and EXTENT_LOCKED cleared. And the involved folios will be properly submitted, with their dirty flags cleared during submission. For the error path, it will be a little more complex: - The range with ordered extent allocated (range (1)) We only clear the EXTENT_DELALLOC and EXTENT_LOCKED, as the remaining flags are cleaned up by btrfs_mark_ordered_io_finished()->btrfs_finish_one_ordered(). For folios we finish the IO (clear dirty, start writeback and immediately finish the writeback) and unlock the folios. - The range with reserved extent but no ordered extent (range(2)) - The range we never touched (range(3)) For both range (2) and range(3) the behavior is not changed. Now even if cow_file_range() failed halfway with some successfully reserved extents/ordered extents, we will keep all folios clean, so there will be no future writeback triggered on them.

[PATCH OLK-6.6] misc: fastrpc: Fix copy buffer page size

25 Mar '25

From: Ekansh Gupta <quic_ekangupt(a)quicinc.com> stable inclusion from stable-v6.6.78 commit c0464bad0e85fcd5d47e4297d1e410097c979e55 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPC3E CVE: CVE-2025-21734 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit e966eae72762ecfdbdb82627e2cda48845b9dd66 upstream. For non-registered buffer, fastrpc driver copies the buffer and pass it to the remote subsystem. There is a problem with current implementation of page size calculation which is not considering the offset in the calculation. This might lead to passing of improper and out-of-bounds page size which could result in memory issue. Calculate page start and page end using the offset adjusted address instead of absolute address.

The current code directly frees the device after calling device_add() without waiting for other kernel parts to release their references. Thus, a reference could still be held to a struct device, e.g., by sysfs, leading to potential use-after-free issues if a proper release function is not set.

[PATCH OLK-6.6] ASoC: soc-pcm: don't use soc_pcm_ret() on .prepare callback
by Qi Xi 25 Mar '25

25 Mar '25

From: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> mainline inclusion from mainline-v6.14-rc1 commit 301c26a018acb94dd537a4418cefa0f654500c6f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBRED3 CVE: CVE-2024-58077 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- commit 1f5664351410 ("ASoC: lower "no backend DAIs enabled for ... Port" log severity") ignores -EINVAL error message on common soc_pcm_ret(). It is used from many functions, ignoring -EINVAL is over-kill. The reason why -EINVAL was ignored was it really should only be used upon invalid parameters coming from userspace and in that case we don't want to log an error since we do not want to give userspace a way to do a denial-of-service attack on the syslog / diskspace. So don't use soc_pcm_ret() on .prepare callback is better idea.

[PATCH OLK-6.6] perf/core: Order the PMU list to fix warning about unordered pmu_ctx_list
by Luo Gengkun 21 Mar '25

21 Mar '25

From: Luo Gengkun <luogengkun(a)huaweicloud.com> stable inclusion from stable-v6.6.81 commit f0c3971405cef6892844016aa710121a02da3a23 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBUX7R Reference: https://git.kernel.org/stable/c/f0c3971405cef6892844016aa710121a02da3a23 -------------------------------- [ Upstream commit 2016066c66192a99d9e0ebf433789c490a6785a2 ] Syskaller triggers a warning due to prev_epc->pmu != next_epc->pmu in perf_event_swap_task_ctx_data(). vmcore shows that two lists have the same perf_event_pmu_context, but not in the same order. The problem is that the order of pmu_ctx_list for the parent is impacted by the time when an event/PMU is added. While the order for a child is impacted by the event order in the pinned_groups and flexible_groups. So the order of pmu_ctx_list in the parent and child may be different. To fix this problem, insert the perf_event_pmu_context to its proper place after iteration of the pmu_ctx_list. The follow testcase can trigger above warning: # perf record -e cycles --call-graph lbr -- taskset -c 3 ./a.out & # perf stat -e cpu-clock,cs -p xxx // xxx is the pid of a.out test.c void main() { int count = 0; pid_t pid; printf("%d running\n", getpid()); sleep(30); printf("running\n"); pid = fork(); if (pid == -1) { printf("fork error\n"); return; } if (pid == 0) { while (1) { count++; } } else { while (1) { count++; } } } The testcase first opens an LBR event, so it will allocate task_ctx_data, and then open tracepoint and software events, so the parent context will have 3 different perf_event_pmu_contexts. On inheritance, child ctx will insert the perf_event_pmu_context in another order and the warning will trigger.

[PATCH openEuler-1.0-LTS] mm/hugetlb: fix surplus pages in dissolve_free_huge_page()
by Jinjiang Tu 21 Mar '25

21 Mar '25

mainline inclusion from mainline-v6.14-rc6 commit cb402bbdabcaa5a765068c5b8673bbfc1c264242 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBV73U CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ------------------------------------------- In dissolve_free_huge_page(), free huge pages are dissolved without adjusting surplus count. However, free huge pages may be accounted as surplus pages, and will lead to wrong surplus count. I reproduce this issue on qemu. The steps are: 1) Node1 is memory-less at first. Hot-add memory to node1 by executing the two commands in qemu monitor: object_add memory-backend-ram,id=mem1,size=1G device_add pc-dimm,id=dimm1,memdev=mem1,node=1 2) online one memory block of Node1 with： echo online_movable > /sys/devices/system/node/node1/memoryX/state 3) create 64 huge pages for node1 4) run a program to reserve (don't consume) all the huge pages 5) echo 0 > nr_huge_pages for node1. After this step, free huge pages in Node1 are surplus. 6) create 80 huge pages for node0 7) offline memory of node1, The memory range to offline contains the free surplus huge pages created in step3) ~ step5) echo offline > /sys/devices/system/node/node1/memoryX/state 8) kill the program in step 4) The result: Node0 Node1 total 80 0 free 80 0 surplus 0 61 To fix it, adjust surplus when destroying huge pages if the node has surplus pages in dissolve_free_hugetlb_folio(). The result with this patch: Node0 Node1 total 80 0 free 80 0 surplus 0 0 Link: https://lkml.kernel.org/r/20250304132106.2872754-1-tujinjiang@huawei.com Fixes: c8721bbbdd36 ("mm: memory-hotplug: enable memory hotplug to handle hugepage") Signed-off-by: Jinjiang Tu <tujinjiang(a)huawei.com> Acked-by: David Hildenbrand <david(a)redhat.com> Acked-by: Oscar Salvador <osalvador(a)suse.de> Cc: Jinjiang Tu <tujinjiang(a)huawei.com> Cc: Kefeng Wang <wangkefeng.wang(a)huawei.com> Cc: Muchun Song <muchun.song(a)linux.dev> Cc: Nanyong Sun <sunnanyong(a)huawei.com> Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> Conflicts: mm/hugetlb.c [Context conflicts, and HVO isn't introduced, so don't need to handle HVO err case.] Signed-off-by: Jinjiang Tu <tujinjiang(a)huawei.com> --- mm/hugetlb.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/mm/hugetlb.c b/mm/hugetlb.c index 69dd1e096a48..ac6f18afdf76 100644 --- a/mm/hugetlb.c +++ b/mm/hugetlb.c @@ -1823,6 +1823,7 @@ int dissolve_free_huge_page(struct page *page) if (!page_count(page)) { struct page *head = compound_head(page); struct hstate *h = page_hstate(head); + bool adjust_surplus = false; if (h->free_huge_pages - h->resv_huge_pages == 0) goto out; @@ -1853,7 +1854,9 @@ int dissolve_free_huge_page(struct page *page) SetPageHWPoison(page); ClearPageHWPoison(head); } - remove_hugetlb_page(h, head, false); + if (h->surplus_huge_pages_node[page_to_nid(head)]) + adjust_surplus = true; + remove_hugetlb_page(h, head, adjust_surplus); h->max_huge_pages--; spin_unlock_irq(&hugetlb_lock); update_and_free_page(h, head); -- 2.43.0

[PATCH openEuler-1.0-LTS] mm/hugetlb: fix surplus pages in dissolve_free_huge_page()
by Jinjiang Tu 21 Mar '25

21 Mar '25

mainline inclusion from mainline-v6.14-rc6 commit cb402bbdabcaa5a765068c5b8673bbfc1c264242 category: bugfix bugzilla: 190517 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ------------------------------------------- In dissolve_free_huge_page(), free huge pages are dissolved without adjusting surplus count. However, free huge pages may be accounted as surplus pages, and will lead to wrong surplus count. I reproduce this issue on qemu. The steps are: 1) Node1 is memory-less at first. Hot-add memory to node1 by executing the two commands in qemu monitor: object_add memory-backend-ram,id=mem1,size=1G device_add pc-dimm,id=dimm1,memdev=mem1,node=1 2) online one memory block of Node1 with： echo online_movable > /sys/devices/system/node/node1/memoryX/state 3) create 64 huge pages for node1 4) run a program to reserve (don't consume) all the huge pages 5) echo 0 > nr_huge_pages for node1. After this step, free huge pages in Node1 are surplus. 6) create 80 huge pages for node0 7) offline memory of node1, The memory range to offline contains the free surplus huge pages created in step3) ~ step5) echo offline > /sys/devices/system/node/node1/memoryX/state 8) kill the program in step 4) The result: Node0 Node1 total 80 0 free 80 0 surplus 0 61 To fix it, adjust surplus when destroying huge pages if the node has surplus pages in dissolve_free_hugetlb_folio(). The result with this patch: Node0 Node1 total 80 0 free 80 0 surplus 0 0 Link: https://lkml.kernel.org/r/20250304132106.2872754-1-tujinjiang@huawei.com Fixes: c8721bbbdd36 ("mm: memory-hotplug: enable memory hotplug to handle hugepage") Signed-off-by: Jinjiang Tu <tujinjiang(a)huawei.com> Acked-by: David Hildenbrand <david(a)redhat.com> Acked-by: Oscar Salvador <osalvador(a)suse.de> Cc: Jinjiang Tu <tujinjiang(a)huawei.com> Cc: Kefeng Wang <wangkefeng.wang(a)huawei.com> Cc: Muchun Song <muchun.song(a)linux.dev> Cc: Nanyong Sun <sunnanyong(a)huawei.com> Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> Conflicts: mm/hugetlb.c [Context conflicts, and HVO isn't introduced, so don't need to handle HVO err case.] Signed-off-by: Jinjiang Tu <tujinjiang(a)huawei.com> --- mm/hugetlb.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/mm/hugetlb.c b/mm/hugetlb.c index 69dd1e096a48..ac6f18afdf76 100644 --- a/mm/hugetlb.c +++ b/mm/hugetlb.c @@ -1823,6 +1823,7 @@ int dissolve_free_huge_page(struct page *page) if (!page_count(page)) { struct page *head = compound_head(page); struct hstate *h = page_hstate(head); + bool adjust_surplus = false; if (h->free_huge_pages - h->resv_huge_pages == 0) goto out; @@ -1853,7 +1854,9 @@ int dissolve_free_huge_page(struct page *page) SetPageHWPoison(page); ClearPageHWPoison(head); } - remove_hugetlb_page(h, head, false); + if (h->surplus_huge_pages_node[page_to_nid(head)]) + adjust_surplus = true; + remove_hugetlb_page(h, head, adjust_surplus); h->max_huge_pages--; spin_unlock_irq(&hugetlb_lock); update_and_free_page(h, head); -- 2.43.0

From: Pavel Begunkov <asml.silence(a)gmail.com> stable inclusion from stable-v6.6.78 commit 146a185f6c05ee263db715f860620606303c4633 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBRNOR CVE: CVE-2025-21836 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=… -------------------------------- commit 8802766324e1f5d414a81ac43365c20142e85603 upstream. IORING_REGISTER_PBUF_RING can reuse an old struct io_buffer_list if it was created for legacy selected buffer and has been emptied.

[PATCH openEuler-1.0-LTS] scsi: lpfc: Fix null pointer dereference after failing to issue FLOGI and PLOGI
by Guo Mengqi 19 Mar '25

19 Mar '25

From: James Smart <jsmart2021(a)gmail.com> mainline inclusion from mainline-v5.19-rc1 commit 577a942df3de2666f6947bdd3a5c9e8d30073424 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP6SH CVE: CVE-2022-49535 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- [ Upstream commit 577a942df3de2666f6947bdd3a5c9e8d30073424 ] If lpfc_issue_els_flogi() fails and returns non-zero status, the node reference count is decremented to trigger the release of the nodelist structure. However, if there is a prior registration or dev-loss-evt work pending, the node may be released prematurely. When dev-loss-evt completes, the released node is referenced causing a use-after-free null pointer dereference. Similarly, when processing non-zero ELS PLOGI completion status in lpfc_cmpl_els_plogi(), the ndlp flags are checked for a transport registration before triggering node removal. If dev-loss-evt work is pending, the node may be released prematurely and a subsequent call to lpfc_dev_loss_tmo_handler() results in a use after free ndlp dereference. Add test for pending dev-loss before decrementing the node reference count for FLOGI, PLOGI, PRLI, and ADISC handling.

[PATCH OLK-6.6 1/2] bpf: unify VM_WRITE vs VM_MAYWRITE use in BPF map mmaping logic
by Pu Lehui 19 Mar '25

19 Mar '25

From: Andrii Nakryiko <andrii(a)kernel.org> stable inclusion from stable-v6.6.80 commit fc01ba097319ae2033f118da3075bd783f4a08e9 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBSW0M CVE: CVE-2025-21853 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 98671a0fd1f14e4a518ee06b19037c20014900eb ] For all BPF maps we ensure that VM_MAYWRITE is cleared when memory-mapping BPF map contents as initially read-only VMA. This is because in some cases BPF verifier relies on the underlying data to not be modified afterwards by user space, so once something is mapped read-only, it shouldn't be re-mmap'ed as read-write. As such, it's not necessary to check VM_MAYWRITE in bpf_map_mmap() and map->ops->map_mmap() callbacks: VM_WRITE should be consistently set for read-write mappings, and if VM_WRITE is not set, there is no way for user space to upgrade read-only mapping to read-write one. This patch cleans up this VM_WRITE vs VM_MAYWRITE handling within bpf_map_mmap(), which is an entry point for any BPF map mmap()-ing logic. We also drop unnecessary sanitization of VM_MAYWRITE in BPF ringbuf's map_mmap() callback implementation, as it is already performed by common code in bpf_map_mmap(). Note, though, that in bpf_map_mmap_{open,close}() callbacks we can't drop VM_MAYWRITE use, because it's possible (and is outside of subsystem's control) to have initially read-write memory mapping, which is subsequently dropped to read-only by user space through mprotect(). In such case, from BPF verifier POV it's read-write data throughout the lifetime of BPF map, and is counted as "active writer". But its VMAs will start out as VM_WRITE|VM_MAYWRITE, then mprotect() can change it to just VM_MAYWRITE (and no VM_WRITE), so when its finally munmap()'ed and bpf_map_mmap_close() is called, vm_flags will be just VM_MAYWRITE, but we still need to decrement active writer count with bpf_map_write_active_dec() as it's still considered to be a read-write mapping by the rest of BPF subsystem. Similar reasoning applies to bpf_map_mmap_open(), which is called whenever mmap(), munmap(), and/or mprotect() forces mm subsystem to split original VMA into multiple discontiguous VMAs. Memory-mapping handling is a bit tricky, yes.

When tcmu_try_get_data_page() returns, the returned page may have been freed by tcmu_blocks_release(). We need to get_page() under cmdr_lock to avoid concurrent tcmu_blocks_release().

[PATCH OLK-6.6] media: uvcvideo: Fix crash during unbind if gpio unit is in use
by Zhang Kunbo 17 Mar '25

17 Mar '25

From: Ricardo Ribalda <ribalda(a)chromium.org> stable inclusion from stable-v6.6.78 commit 0b5e0445bc8384c18bd35cb9fe87f6258c6271d9 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBRED4 CVE: CVE-2024-58079 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit a9ea1a3d88b7947ce8cadb2afceee7a54872bbc5 upstream. We used the wrong device for the device managed functions. We used the usb device, when we should be using the interface device. If we unbind the driver from the usb interface, the cleanup functions are never called. In our case, the IRQ is never disabled. If an IRQ is triggered, it will try to access memory sections that are already free, causing an OOPS. We cannot use the function devm_request_threaded_irq here. The devm_* clean functions may be called after the main structure is released by uvc_delete. Luckily this bug has small impact, as it is only affected by devices with gpio units and the user has to unbind the device, a disconnect will not trigger this error.

[PATCH openEuler-1.0-LTS] ath9k_htc: fix uninit value bugs
by He Yujie 15 Mar '25

15 Mar '25

From: Pavel Skripkin <paskripkin(a)gmail.com> stable inclusion from stable-v4.19.238 commit ee4222052a76559c20e821bc3519cefb58b6d3e9 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP2I0 CVE: CVE-2022-49235 Reference: https://web.git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit… -------------------------------- [ Upstream commit d1e0df1c57bd30871dd1c855742a7c346dbca853 ] Syzbot reported 2 KMSAN bugs in ath9k. All of them are caused by missing field initialization. In htc_connect_service() svc_meta_len and pad are not initialized. Based on code it looks like in current skb there is no service data, so simply initialize svc_meta_len to 0. htc_issue_send() does not initialize htc_frame_hdr::control array. Based on firmware code, it will initialize it by itself, so simply zero whole array to make KMSAN happy Fail logs: BUG: KMSAN: kernel-usb-infoleak in usb_submit_urb+0x6c1/0x2aa0 drivers/usb/core/urb.c:430 usb_submit_urb+0x6c1/0x2aa0 drivers/usb/core/urb.c:430 hif_usb_send_regout drivers/net/wireless/ath/ath9k/hif_usb.c:127 [inline] hif_usb_send+0x5f0/0x16f0 drivers/net/wireless/ath/ath9k/hif_usb.c:479 htc_issue_send drivers/net/wireless/ath/ath9k/htc_hst.c:34 [inline] htc_connect_service+0x143e/0x1960 drivers/net/wireless/ath/ath9k/htc_hst.c:275 ...

All of them are caused by missing field initialization. In htc_connect_service() svc_meta_len and pad are not initialized. Based on code it looks like in current skb there is no service data, so simply initialize svc_meta_len to 0. htc_issue_send() does not initialize htc_frame_hdr::control array. Based on firmware code, it will initialize it by itself, so simply zero whole array to make KMSAN happy Fail logs: BUG: KMSAN: kernel-usb-infoleak in usb_submit_urb+0x6c1/0x2aa0 drivers/usb/core/urb.c:430 usb_submit_urb+0x6c1/0x2aa0 drivers/usb/core/urb.c:430 hif_usb_send_regout drivers/net/wireless/ath/ath9k/hif_usb.c:127 [inline] hif_usb_send+0x5f0/0x16f0 drivers/net/wireless/ath/ath9k/hif_usb.c:479 htc_issue_send drivers/net/wireless/ath/ath9k/htc_hst.c:34 [inline] htc_connect_service+0x143e/0x1960 drivers/net/wireless/ath/ath9k/htc_hst.c:275 ...

Therefore, the two locks can be concurrent. ctrl_cdev_ioctl contains two operations: ubi_attach and ubi_detach. ubi_detach is bug-free because it uses reference counting to prevent concurrency. However, uif_init and uif_close in ubi_attach may race with ubi_cdev_ioctl. uif_init will race with ubi_cdev_ioctl as in the following stack. cpu1 cpu2 cpu3 _______________________|________________________|______________________ ctrl_cdev_ioctl ubi_attach_mtd_dev uif_init ubi_cdev_ioctl ubi_create_volume cdev_device_add ubi_add_volume // sysfs exist kill_volumes ubi_cdev_ioctl ubi_remove_volume cdev_device_del // first free ubi_free_volume cdev_del // double free cdev_device_del And uif_close will race with ubi_cdev_ioctl as in the following stack. cpu1 cpu2 cpu3 _______________________|________________________|______________________ ctrl_cdev_ioctl ubi_attach_mtd_dev uif_init ubi_cdev_ioctl ubi_create_volume cdev_device_add ubi_debugfs_init_dev //error goto out_uif; uif_close kill_volumes ubi_cdev_ioctl ubi_remove_volume cdev_device_del // first free ubi_free_volume // double free The cause of this problem is that commit 714fb87e8bc0 make device "available" before it becomes accessible via sysfs. Therefore, we roll back the modification. We will fix the race condition between ubi device creation and udev by removing ubi_get_device in vol_attribute_show and dev_attribute_show.This avoids accessing uninitialized ubi_devices[ubi_num]. ubi_get_device is used to prevent devices from being deleted during sysfs execution. However, now kernfs ensures that devices will not be deleted before all reference counting are released. The key process is shown in the following stack. device_del device_remove_attrs device_remove_groups sysfs_remove_groups sysfs_remove_group remove_files kernfs_remove_by_name kernfs_remove_by_name_ns __kernfs_remove kernfs_drain Fixes: 714fb87e8bc0 ("ubi: Fix race condition between ubi device creation and udev") Reported-by: Hulk Robot <hulkci(a)huawei.com> Signed-off-by: Baokun Li <libaokun1(a)huawei.com> Signed-off-by: Richard Weinberger <richard(a)nod.at> Conflicts: drivers/mtd/ubi/build.c [Not merged: fc55dacf7fea and its prerequisite patches.] Signed-off-by: Wang Zhaolong <wangzhaolong1(a)huawei.com> --- drivers/mtd/ubi/build.c | 9 +-------- drivers/mtd/ubi/vmt.c | 8 +------- 2 files changed, 2 insertions(+), 15 deletions(-) diff --git a/drivers/mtd/ubi/build.c b/drivers/mtd/ubi/build.c index 93cce95287ba..d15c6a64f7cd 100644 --- a/drivers/mtd/ubi/build.c +++ b/drivers/mtd/ubi/build.c @@ -361,13 +361,10 @@ static ssize_t dev_attribute_show(struct device *dev, * * Remember, 'struct ubi_device' is freed in the release function, so * we still can use 'ubi->ubi_num'. */ ubi = container_of(dev, struct ubi_device, dev); - ubi = ubi_get_device(ubi->ubi_num); - if (!ubi) - return -ENODEV; if (attr == &dev_eraseblock_size) ret = sprintf(buf, "%d\n", ubi->leb_size); else if (attr == &dev_avail_eraseblocks) ret = sprintf(buf, "%d\n", ubi->avail_pebs); @@ -392,11 +389,10 @@ static ssize_t dev_attribute_show(struct device *dev, else if (attr == &dev_ro_mode) ret = sprintf(buf, "%d\n", ubi->ro_mode); else ret = -EINVAL; - ubi_put_device(ubi); return ret; } static struct attribute *ubi_dev_attrs[] = { &dev_eraseblock_size.attr, @@ -974,13 +970,10 @@ int ubi_attach_mtd_dev(struct mtd_info *mtd, int ubi_num, err = autoresize(ubi, ubi->autoresize_vol_id); if (err) goto out_detach; } - /* Make device "available" before it becomes accessible via sysfs */ - ubi_devices[ubi_num] = ubi; - err = uif_init(ubi); if (err) goto out_detach; err = ubi_debugfs_init_dev(ubi); @@ -1021,19 +1014,19 @@ int ubi_attach_mtd_dev(struct mtd_info *mtd, int ubi_num, spin_lock(&ubi->wl_lock); ubi->thread_enabled = 1; wake_up_process(ubi->bgt_thread); spin_unlock(&ubi->wl_lock); + ubi_devices[ubi_num] = ubi; ubi_notify_all(ubi, UBI_VOLUME_ADDED, NULL); return ubi_num; out_debugfs: ubi_debugfs_exit_dev(ubi); out_uif: uif_close(ubi); out_detach: - ubi_devices[ubi_num] = NULL; ubi_wl_close(ubi); ubi_free_internal_volumes(ubi); vfree(ubi->vtbl); out_free: vfree(ubi->peb_buf); diff --git a/drivers/mtd/ubi/vmt.c b/drivers/mtd/ubi/vmt.c index 729588b94e41..d0c6b66b7450 100644 --- a/drivers/mtd/ubi/vmt.c +++ b/drivers/mtd/ubi/vmt.c @@ -67,20 +67,15 @@ static struct device_attribute attr_vol_upd_marker = static ssize_t vol_attribute_show(struct device *dev, struct device_attribute *attr, char *buf) { int ret; struct ubi_volume *vol = container_of(dev, struct ubi_volume, dev); - struct ubi_device *ubi; - - ubi = ubi_get_device(vol->ubi->ubi_num); - if (!ubi) - return -ENODEV; + struct ubi_device *ubi = vol->ubi; spin_lock(&ubi->volumes_lock); if (!ubi->volumes[vol->vol_id]) { spin_unlock(&ubi->volumes_lock); - ubi_put_device(ubi); return -ENODEV; } /* Take a reference to prevent volume removal */ vol->ref_count += 1; spin_unlock(&ubi->volumes_lock); @@ -114,11 +109,10 @@ static ssize_t vol_attribute_show(struct device *dev, /* We've done the operation, drop volume and UBI device references */ spin_lock(&ubi->volumes_lock); vol->ref_count -= 1; ubi_assert(vol->ref_count >= 0); spin_unlock(&ubi->volumes_lock); - ubi_put_device(ubi); return ret; } static struct attribute *volume_dev_attrs[] = { &attr_vol_reserved_ebs.attr, -- 2.34.3

In ieee80211_vif_use_reserved_context(), when we have an old context and the new context's replace_state is set to IEEE80211_CHANCTX_REPLACE_NONE, we free the old context in ieee80211_vif_use_reserved_reassign().

However, since the new_ctx replace state is clearly not IEEE80211_CHANCTX_REPLACES_OTHER, we're not going to do anything else in this function and can just return to avoid accessing the freed old_ctx.

[PATCH openEuler-1.0-LTS] dlm: fix plock invalid read
by Xia Fukun 14 Mar '25

14 Mar '25

From: Alexander Aring <aahringo(a)redhat.com> stable inclusion from stable-v4.19.247 commit 5a1765adf9855cf0f6d3f7e0eb4b78ca66f70dee category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP3TG CVE: CVE-2022-49407 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 42252d0d2aa9b94d168241710a761588b3959019 upstream. This patch fixes an invalid read showed by KASAN. A unlock will allocate a "struct plock_op" and a followed send_op() will append it to a global send_list data structure. In some cases a followed dev_read() moves it to recv_list and dev_write() will cast it to "struct plock_xop" and access fields which are only available in those structures. At this point an invalid read happens by accessing those fields. To fix this issue the "callback" field is moved to "struct plock_op" to indicate that a cast to "plock_xop" is allowed and does the additional "plock_xop" handling if set. Example of the KASAN output which showed the invalid read: [ 2064.296453] ================================================================== [ 2064.304852] BUG: KASAN: slab-out-of-bounds in

[PATCH openEuler-1.0-LTS] mm: fix unexpected zeroed page mapping with zram swap
by Liu Shixin 14 Mar '25

14 Mar '25

From: Minchan Kim <minchan(a)kernel.org> stable inclusion from stable-v4.19.242 commit f86d55cf616199404c05f5b0c5c41b17351baa02 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP28G CVE: CVE-2022-49052 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit e914d8f00391520ecc4495dd0ca0124538ab7119 upstream. Two processes under CLONE_VM cloning, user process can be corrupted by seeing zeroed page unexpectedly. CPU A CPU B do_swap_page do_swap_page SWP_SYNCHRONOUS_IO path SWP_SYNCHRONOUS_IO path swap_readpage valid data swap_slot_free_notify delete zram entry swap_readpage zeroed(invalid) data pte_lock map the *zero data* to userspace pte_unlock pte_lock if (!pte_same) goto out_nomap; pte_unlock return and next refault will read zeroed data The swap_slot_free_notify is bogus for CLONE_VM case since it doesn't increase the refcount of swap slot at copy_mm so it couldn't catch up whether it's safe or not to discard data from backing device. In the case, only the lock it could rely on to synchronize swap slot freeing is page table lock. Thus, this patch gets rid of the swap_slot_free_notify function. With this patch, CPU A will see correct data. CPU A CPU B do_swap_page do_swap_page SWP_SYNCHRONOUS_IO path SWP_SYNCHRONOUS_IO path swap_readpage original data pte_lock map the original data swap_free swap_range_free bd_disk->fops->swap_slot_free_notify swap_readpage read zeroed data pte_unlock pte_lock if (!pte_same) goto out_nomap; pte_unlock return on next refault will see mapped data by CPU B The concern of the patch would increase memory consumption since it could keep wasted memory with compressed form in zram as well as uncompressed form in address space. However, most of cases of zram uses no readahead and do_swap_page is followed by swap_free so it will free the compressed form from in zram quickly.

[PATCH OLK-5.10] PCI: rcar-ep: Fix incorrect variable used when calling devm_request_mem_region()

From: King Dix <kingdix10(a)qq.com> mainline inclusion from mainline-v6.14-rc1 commit 2d2da5a4c1b4509f6f7e5a8db015cd420144beb4 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPLK2 CVE: CVE-2025-21804 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The rcar_pcie_parse_outbound_ranges() uses the devm_request_mem_region() macro to request a needed resource. A string variable that lives on the stack is then used to store a dynamically computed resource name, which is then passed on as one of the macro arguments. This can lead to undefined behavior. Depending on the current contents of the memory, the manifestations of errors may vary. One possible output may be as follows: $ cat /proc/iomem 30000000-37ffffff : 38000000-3fffffff : Sometimes, garbage may appear after the colon. In very rare cases, if no NULL-terminator is found in memory, the system might crash because the string iterator will overrun which can lead to access of unmapped memory above the stack. Thus, fix this by replacing outbound_name with the name of the previously requested resource.

[PATCH OLK-6.6] hrtimers: Force migrate away hrtimers queued after CPUHP_AP_HRTIMERS_DYING
by Xiongfeng Wang 13 Mar '25

13 Mar '25

From: Frederic Weisbecker <frederic(a)kernel.org> mainline inclusion from mainline-v6.14-rc2 commit 53dac345395c0d2493cbc2f4c85fe38aef5b63f5 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPLI0 CVE: CVE-2025-21816 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- hrtimers are migrated away from the dying CPU to any online target at the CPUHP_AP_HRTIMERS_DYING stage in order not to delay bandwidth timers handling tasks involved in the CPU hotplug forward progress. However wakeups can still be performed by the outgoing CPU after CPUHP_AP_HRTIMERS_DYING. Those can result again in bandwidth timers being armed. Depending on several considerations (crystal ball power management based election, earliest timer already enqueued, timer migration enabled or not), the target may eventually be the current CPU even if offline. If that happens, the timer is eventually ignored. The most notable example is RCU which had to deal with each and every of those wake-ups by deferring them to an online CPU, along with related workarounds: _ e787644caf76 (rcu: Defer RCU kthreads wakeup when CPU is dying) _ 9139f93209d1 (rcu/nocb: Fix RT throttling hrtimer armed from offline CPU) _ f7345ccc62a4 (rcu/nocb: Fix rcuog wake-up from offline softirq) The problem isn't confined to RCU though as the stop machine kthread (which runs CPUHP_AP_HRTIMERS_DYING) reports its completion at the end of its work through cpu_stop_signal_done() and performs a wake up that eventually arms the deadline server timer: WARNING: CPU: 94 PID: 588 at kernel/time/hrtimer.c:1086 hrtimer_start_range_ns+0x289/0x2d0 CPU: 94 UID: 0 PID: 588 Comm: migration/94 Not tainted Stopper: multi_cpu_stop+0x0/0x120 <- stop_machine_cpuslocked+0x66/0xc0 RIP: 0010:hrtimer_start_range_ns+0x289/0x2d0 Call Trace: <TASK> start_dl_timer enqueue_dl_entity dl_server_start enqueue_task_fair enqueue_task ttwu_do_activate try_to_wake_up complete cpu_stopper_thread Instead of providing yet another bandaid to work around the situation, fix it in the hrtimers infrastructure instead: always migrate away a timer to an online target whenever it is enqueued from an offline CPU. This will also allow to revert all the above RCU disgraceful hacks.

[PATCH OLK-6.6] PCI: rcar-ep: Fix incorrect variable used when calling devm_request_mem_region()

From: King Dix <kingdix10(a)qq.com> stable inclusion from stable-v6.6.76 commit 2c54b9fca1755e80a343ccfde0652dc5ea4744b2 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPLK2 CVE: CVE-2025-21804 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 2d2da5a4c1b4509f6f7e5a8db015cd420144beb4 ] The rcar_pcie_parse_outbound_ranges() uses the devm_request_mem_region() macro to request a needed resource. A string variable that lives on the stack is then used to store a dynamically computed resource name, which is then passed on as one of the macro arguments. This can lead to undefined behavior. Depending on the current contents of the memory, the manifestations of errors may vary. One possible output may be as follows: $ cat /proc/iomem 30000000-37ffffff : 38000000-3fffffff : Sometimes, garbage may appear after the colon. In very rare cases, if no NULL-terminator is found in memory, the system might crash because the string iterator will overrun which can lead to access of unmapped memory above the stack. Thus, fix this by replacing outbound_name with the name of the previously requested resource. With the changes applied, the output will be as follows: $ cat /proc/iomem 30000000-37ffffff : memory2 38000000-3fffffff : memory3 Fixes: 2a6d0d63d999 ("PCI: rcar: Add endpoint mode support") Link: https://lore.kernel.org/r/tencent_DBDCC19D60F361119E76919ADAB25EC13C06@qq.c… Tested-by: Lad Prabhakar <prabhakar.mahadev-lad.rj(a)bp.renesas.com> Signed-off-by: King Dix <kingdix10(a)qq.com> [kwilczynski: commit log] Signed-off-by: Krzysztof Wilczyński <kwilczynski(a)kernel.org> Reviewed-by: Lad Prabhakar <prabhakar.mahadev-lad.rj(a)bp.renesas.com> Reviewed-by: Manivannan Sadhasivam <manivannan.sadhasivam(a)linaro.org> Signed-off-by: Sasha Levin <sashal(a)kernel.org> Signed-off-by: ZhangPeng <zhangpeng362(a)huawei.com> Signed-off-by: Xiongfeng Wang <wangxiongfeng2(a)huawei.com> --- drivers/pci/controller/pcie-rcar-ep.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/pci/controller/pcie-rcar-ep.c b/drivers/pci/controller/pcie-rcar-ep.c index f9682df1da61..209719fb6ddc 100644 --- a/drivers/pci/controller/pcie-rcar-ep.c +++ b/drivers/pci/controller/pcie-rcar-ep.c @@ -107,7 +107,7 @@ static int rcar_pcie_parse_outbound_ranges(struct rcar_pcie_endpoint *ep, } if (!devm_request_mem_region(&pdev->dev, res->start, resource_size(res), - outbound_name)) { + res->name)) { dev_err(pcie->dev, "Cannot request memory region %s.\n", outbound_name); return -EIO; -- 2.20.1

[PATCH OLK-6.6] iommufd/iova_bitmap: Fix shift-out-of-bounds in iova_bitmap_offset_to_index()

From: Qasim Ijaz <qasdev00(a)gmail.com> stable inclusion from stable-v6.6.76 commit 38ac76fc06bc6826a3e4b12a98efbe98432380a9 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPBI4 CVE: CVE-2025-21724 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit e24c1551059268b37f6f40639883eafb281b8b9c ] Resolve a UBSAN shift-out-of-bounds issue in iova_bitmap_offset_to_index() where shifting the constant "1" (of type int) by bitmap->mapped.pgshift (an unsigned long value) could result in undefined behavior. The constant "1" defaults to a 32-bit "int", and when "pgshift" exceeds 31 (e.g., pgshift = 63) the shift operation overflows, as the result cannot be represented in a 32-bit type. To resolve this, the constant is updated to "1UL", promoting it to an unsigned long type to match the operand's type.

[PATCH OLK-6.6] PCI: dwc: ep: Prevent changing BAR size/flags in pci_epc_set_bar()
by Xiongfeng Wang 13 Mar '25

13 Mar '25

From: Niklas Cassel <cassel(a)kernel.org> mainline inclusion from mainline-v6.14-rc1 commit 3708acbd5f169ebafe1faa519cb28adc56295546 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPC3J CVE: CVE-2024-58006 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- In commit 4284c88fff0e ("PCI: designware-ep: Allow pci_epc_set_bar() update inbound map address") set_bar() was modified to support dynamically changing the backing physical address of a BAR that was already configured. This means that set_bar() can be called twice, without ever calling clear_bar() (as calling clear_bar() would clear the BAR's PCI address assigned by the host). This can only be done if the new BAR size/flags does not differ from the existing BAR configuration. Add these missing checks. If we allow set_bar() to set e.g. a new BAR size that differs from the existing BAR size, the new address translation range will be smaller than the BAR size already determined by the host, which would mean that a read past the new BAR size would pass the iATU untranslated, which could allow the host to read memory not belonging to the new struct pci_epf_bar. While at it, add comments which clarifies the support for dynamically changing the physical address of a BAR. (Which was also missing.)

[PATCH OLK-6.6] afs: Fix the maximum cell name length

However, the DNS limits the maximum lookup length and, by extension, the maximum cell name, to 255 less two (length count and trailing NUL). Fix this by limiting the maximum acceptable cellname length to 253. This also allows us to be sure we can create the "/afs/.<cell>/" mountpoint too. Further, split the YFS VL record cell name maximum to be the 256 allowed by the protocol and ignore the record retrieved by YFSVL.GetCellName if it exceeds 253.

[PATCH OLK-6.6 v2 1/2] fuse: cleanup request queuing towards virtiofs
by Yang Erkun 13 Mar '25

13 Mar '25

From: Miklos Szeredi <mszeredi(a)redhat.com> mainline inclusion from mainline-v6.12-rc1 commit 5de8acb41c86f1d335d165e0a350441ea3a1f480 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBT4CQ Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- Virtiofs has its own queuing mechanism, but still requests are first queued on fiq->pending to be immediately dequeued and queued onto the virtio queue. The queuing on fiq->pending is unnecessary and might even have some performance impact due to being a contention point. Forget requests are handled similarly. Move the queuing of requests and forgets into the fiq->ops->*. fuse_iqueue_ops are renamed to reflect the new semantics.

[PATCH OLK-5.10] scsi: lpfc: Fix null pointer dereference after failing to issue FLOGI and PLOGI
by Guo Mengqi 13 Mar '25

13 Mar '25

From: James Smart <jsmart2021(a)gmail.com> mainline inclusion from mainline-v5.19-rc1 commit 577a942df3de2666f6947bdd3a5c9e8d30073424 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP6SH CVE: CVE-2022-49535 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- [ Upstream commit 577a942df3de2666f6947bdd3a5c9e8d30073424 ] If lpfc_issue_els_flogi() fails and returns non-zero status, the node reference count is decremented to trigger the release of the nodelist structure. However, if there is a prior registration or dev-loss-evt work pending, the node may be released prematurely. When dev-loss-evt completes, the released node is referenced causing a use-after-free null pointer dereference. Similarly, when processing non-zero ELS PLOGI completion status in lpfc_cmpl_els_plogi(), the ndlp flags are checked for a transport registration before triggering node removal. If dev-loss-evt work is pending, the node may be released prematurely and a subsequent call to lpfc_dev_loss_tmo_handler() results in a use after free ndlp dereference.
