[PATCH OLK-5.10] uprobes: check anon before compound when unregister
by Tengda Wu 02 Jul '25

02 Jul '25

From: Chen Zhongjin <chenzhongjin(a)huawei.com> hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ICJG91 -------------------------------- In uprobe unregister, if the old_page is a compound page, it will trigger a warning and cause the unregister operation to fail: "uprobe unregister should never work on compound page" If old_page is allocated by uprobe through alloc_page_vma(), this page cannot be compounded, so this warning means old_page is a remapped page after register. In this scenario, check PageAnon() first to determine whether the page is a remapped page. Just pass the PageCompound() check and unregister uprobe safely.

[PATCH OLK-6.6] drm/v3d: Add job to pending list if the reset was skipped
by GONG Ruiqi 02 Jul '25

02 Jul '25

From: Maíra Canal <mcanal(a)igalia.com> stable inclusion from stable-v6.6.91 commit 12125f7d9c15e6d8ac91d10373b2db2f17dcf767 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IC9933 CVE: CVE-2025-37951 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 35e4079bf1a2570abffce6ababa631afcf8ea0e5 upstream. When a CL/CSD job times out, we check if the GPU has made any progress since the last timeout. If so, instead of resetting the hardware, we skip the reset and let the timer get rearmed. This gives long-running jobs a chance to complete. However, when `timedout_job()` is called, the job in question is removed from the pending list, which means it won't be automatically freed through `free_job()`. Consequently, when we skip the reset and keep the job running, the job won't be freed when it finally completes. This situation leads to a memory leak, as exposed in [1] and [2]. Similarly to commit 704d3d60fec4 ("drm/etnaviv: don't block scheduler when GPU is still active"), this patch ensures the job is put back on the pending list when extending the timeout.

[PATCH v5.10-next] vhost-scsi: protect vq->log_used with vq->mutex

From: Dongli Zhang <dongli.zhang(a)oracle.com> [ Upstream commit f591cf9fce724e5075cc67488c43c6e39e8cbe27 ] The vhost-scsi completion path may access vq->log_base when vq->log_used is already set to false. vhost-thread QEMU-thread vhost_scsi_complete_cmd_work() -> vhost_add_used() -> vhost_add_used_n() if (unlikely(vq->log_used)) QEMU disables vq->log_used via VHOST_SET_VRING_ADDR. mutex_lock(&vq->mutex); vq->log_used = false now! mutex_unlock(&vq->mutex); QEMU gfree(vq->log_base) log_used() -> log_write(vq->log_base) Assuming the VMM is QEMU. The vq->log_base is from QEMU userpace and can be reclaimed via gfree(). As a result, this causes invalid memory writes to QEMU userspace. The control queue path has the same issue.

[PATCH openEuler-1.0-LTS v3] mm: fix uprobe pte be overwritten when expanding vma
by Pu Lehui 02 Jul '25

02 Jul '25

mainline inclusion from mainline-v6.16-rc1 commit 2b12d06c37fd3a394376f42f026a7478d826ed63 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ICIYRH Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Patch series "Fix uprobe pte be overwritten when expanding vma". This patch (of 4): We encountered a BUG alert triggered by Syzkaller as follows: BUG: Bad rss-counter state mm:00000000b4a60fca type:MM_ANONPAGES val:1 And we can reproduce it with the following steps: 1. register uprobe on file at zero offset 2. mmap the file at zero offset: addr1 = mmap(NULL, 2 * 4096, PROT_NONE, MAP_PRIVATE, fd, 0); 3. mremap part of vma1 to new vma2: addr2 = mremap(addr1, 4096, 2 * 4096, MREMAP_MAYMOVE); 4. mremap back to orig addr1: mremap(addr2, 4096, 4096, MREMAP_MAYMOVE | MREMAP_FIXED, addr1); In step 3, the vma1 range [addr1, addr1 + 4096] will be remap to new vma2 with range [addr2, addr2 + 8192], and remap uprobe anon page from the vma1 to vma2, then unmap the vma1 range [addr1, addr1 + 4096]. In step 4, the vma2 range [addr2, addr2 + 4096] will be remap back to the addr range [addr1, addr1 + 4096]. Since the addr range [addr1 + 4096, addr1 + 8192] still maps the file, it will take vma_merge_new_range to expand the range, and then do uprobe_mmap in vma_complete. Since the merged vma pgoff is also zero offset, it will install uprobe anon page to the merged vma. However, the upcomming move_page_tables step, which use set_pte_at to remap the vma2 uprobe pte to the merged vma, will overwrite the newly uprobe pte in the merged vma, and lead that pte to be orphan. Since the uprobe pte will be remapped to the merged vma, we can remove the unnecessary uprobe_mmap upon merged vma.

[PATCH openEuler-1.0-LTS V1] sched, cpuset: Fix dl_cpu_busy() panic due to empty cs->cpus_allowed
by Zicheng Qu 02 Jul '25

02 Jul '25

From: Waiman Long <longman(a)redhat.com> stable inclusion from stable-v5.10.137 commit 336626564b58071b8980a4e6a31a8f5d92705d9b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICG9AQ CVE: CVE-2022-50103 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- [ Upstream commit b6e8d40d43ae4dec00c8fea2593eeea3114b8f44 ] With cgroup v2, the cpuset's cpus_allowed mask can be empty indicating that the cpuset will just use the effective CPUs of its parent. So cpuset_can_attach() can call task_can_attach() with an empty mask. This can lead to cpumask_any_and() returns nr_cpu_ids causing the call to dl_bw_of() to crash due to percpu value access of an out of bound CPU value. For example: [80468.182258] BUG: unable to handle page fault for address: ffffffff8b6648b0 : [80468.191019] RIP: 0010:dl_cpu_busy+0x30/0x2b0 : [80468.207946] Call Trace: [80468.208947] cpuset_can_attach+0xa0/0x140 [80468.209953] cgroup_migrate_execute+0x8c/0x490 [80468.210931] cgroup_update_dfl_csses+0x254/0x270 [80468.211898] cgroup_subtree_control_write+0x322/0x400 [80468.212854] kernfs_fop_write_iter+0x11c/0x1b0 [80468.213777] new_sync_write+0x11f/0x1b0 [80468.214689] vfs_write+0x1eb/0x280 [80468.215592] ksys_write+0x5f/0xe0 [80468.216463] do_syscall_64+0x5c/0x80 [80468.224287] entry_SYSCALL_64_after_hwframe+0x44/0xae Fix that by using effective_cpus instead. For cgroup v1, effective_cpus is the same as cpus_allowed. For v2, effective_cpus is the real cpumask to be used by tasks within the cpuset anyway. Also update task_can_attach()'s 2nd argument name to cs_effective_cpus to reflect the change. In addition, a check is added to task_can_attach() to guard against the possibility that cpumask_any_and() may return a value >= nr_cpu_ids.

[PATCH OLK-5.10] bpf: fix potential 32-bit overflow when accessing ARRAY map element
by Pu Lehui 01 Jul '25

01 Jul '25

From: Andrii Nakryiko <andrii(a)kernel.org> mainline inclusion from mainline-v6.0-rc1 commit 87ac0d600943994444e24382a87aa19acc4cd3d4 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICGA1J CVE: CVE-2022-50167 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- If BPF array map is bigger than 4GB, element pointer calculation can overflow because both index and elem_size are u32. Fix this everywhere by forcing 64-bit multiplication. Extract this formula into separate small helper and use it consistently in various places. Speculative-preventing formula utilizing index_mask trick is left as is, but explicit u64 casts are added in both places.

[PATCH openEuler-1.0-LTS] wifi: mac80211: Don't finalize CSA in IBSS mode if state is disconnected
by Wang Liang 01 Jul '25

01 Jul '25

From: Siddh Raman Pant <code(a)siddh.me> stable inclusion from stable-v4.19.258 commit d9eb37db6a28b59a95a3461450ee209654c5f95b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICG9HM CVE: CVE-2022-49942 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 15bc8966b6d3a5b9bfe4c9facfa02f2b69b1e5f0 upstream. When we are not connected to a channel, sending channel "switch" announcement doesn't make any sense. The BSS list is empty in that case. This causes the for loop in cfg80211_get_bss() to be bypassed, so the function returns NULL (check line 1424 of net/wireless/scan.c), causing the WARN_ON() in ieee80211_ibss_csa_beacon() to get triggered (check line 500 of net/mac80211/ibss.c), which was consequently reported on the syzkaller dashboard. Thus, check if we have an existing connection before generating the CSA beacon in ieee80211_ibss_finish_csa().

From: Maurizio Lombardi <mlombard(a)redhat.com> mainline inclusion from mainline-v6.14 commit ad95bab0cd28ed77c2c0d0b6e76e03e031391064 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBY43W CVE: CVE-2025-21927 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- nvme_tcp_recv_pdu() doesn't check the validity of the header length.

by Tong Tiangen 01 Jul '25

01 Jul '25

From: Dev Jain <dev.jain(a)arm.com> mainline inclusion from mainline-v6.16-rc1 commit 4a34c584d8cd13d2b721d21cf629f77c60bfb4a4 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICF4UI CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ------------------------------------------- After the check for queue_folio_required(), the code only cares about the folio in the for loop, i.e the PTEs are redundant. Therefore, optimize this loop by skipping over a PTE batch mapping the same folio. With a test program migrating pages of the calling process, which includes a mapped VMA of size 4GB with pte-mapped large folios of order-9, and migrating once back and forth node-0 and node-1, the average execution time reduces from 7.5 to 4 seconds, giving an approx 47% speedup.

[PATCH OLK-5.10,V2] nvme-tcp: fix potential memory corruption in nvme_tcp_recv_pdu()
by Yi Yang 01 Jul '25

01 Jul '25

From: Maurizio Lombardi <mlombard(a)redhat.com> mainline inclusion from mainline-v6.14 commit ad95bab0cd28ed77c2c0d0b6e76e03e031391064 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBY43W CVE: CVE-2025-21927 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- nvme_tcp_recv_pdu() doesn't check the validity of the header length. When header digests are enabled, a target might send a packet with an invalid header length (e.g. 255), causing nvme_tcp_verify_hdgst() to access memory outside the allocated area and cause memory corruptions by overwriting it with the calculated digest. Fix this by rejecting packets with an unexpected header length.
