[PATCH OLK-6.6] bpf, arm64: Do not audit capability check in do_jit()
by Pu Lehui 22 Dec '25

22 Dec '25

From: Ondrej Mosnacek <omosnace(a)redhat.com> mainline inclusion from mainline-v6.19-rc2 commit 189e5deb944a6f9c7992355d60bffd8ec2e54a9c category: bugfix bugzilla: https://atomgit.com/src-openeuler/kernel/issues/12686 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Analogically to the x86 commit 881a9c9cb785 ("bpf: Do not audit capability check in do_jit()"), change the capable() call to ns_capable_noaudit() in order to avoid spurious SELinux denials in audit log. The commit log from that commit applies here as well: """ The failure of this check only results in a security mitigation being applied, slightly affecting performance of the compiled BPF program. It doesn't result in a failed syscall, an thus auditing a failed LSM permission check for it is unwanted. For example with SELinux, it causes a denial to be reported for confined processes running as root, which tends to be flagged as a problem to be fixed in the policy. Yet dontauditing or allowing CAP_SYS_ADMIN to the domain may not be desirable, as it would allow/silence also other checks - either going against the principle of least privilege or making debugging potentially harder. Fix it by changing it from capable() to ns_capable_noaudit(), which instructs the LSMs to not audit the resulting denials.

[PATCH OLK-6.6] ext4: add i_data_sem protection in ext4_destroy_inline_data_nolock()

From: Alexey Nepomnyashih <sdl(a)nppct.ru> mainline inclusion from mainline-v6.19-rc1 commit 0cd8feea8777f8d9b9a862b89c688b049a5c8475 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IDDF1F CVE: CVE-2025-68261 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Fix a race between inline data destruction and block mapping. The function ext4_destroy_inline_data_nolock() changes the inode data layout by clearing EXT4_INODE_INLINE_DATA and setting EXT4_INODE_EXTENTS. At the same time, another thread may execute ext4_map_blocks(), which tests EXT4_INODE_EXTENTS to decide whether to call ext4_ext_map_blocks() or ext4_ind_map_blocks(). Without i_data_sem protection, ext4_ind_map_blocks() may receive inode with EXT4_INODE_EXTENTS flag and triggering assert. kernel BUG at fs/ext4/indirect.c:546!

[PATCH OLK-6.6] ext4: refresh inline data size before write operations
by Yongjian Sun 22 Dec '25

22 Dec '25

From: Deepanshu Kartikey <kartikey406(a)gmail.com> mainline inclusion from mainline-v6.19-rc1 commit 892e1cf17555735e9d021ab036c36bc7b58b0e3b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IDDF27 CVE: CVE-2025-68264 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The cached ei->i_inline_size can become stale between the initial size check and when ext4_update_inline_data()/ext4_create_inline_data() use it. Although ext4_get_max_inline_size() reads the correct value at the time of the check, concurrent xattr operations can modify i_inline_size before ext4_write_lock_xattr() is acquired. This causes ext4_update_inline_data() and ext4_create_inline_data() to work with stale capacity values, leading to a BUG_ON() crash in ext4_write_inline_data(): kernel BUG at fs/ext4/inline.c:1331! BUG_ON(pos + len > EXT4_I(inode)->i_inline_size); The race window: 1. ext4_get_max_inline_size() reads i_inline_size = 60 (correct) 2. Size check passes for 50-byte write 3. [Another thread adds xattr, i_inline_size changes to 40] 4. ext4_write_lock_xattr() acquires lock 5. ext4_update_inline_data() uses stale i_inline_size = 60 6. Attempts to write 50 bytes but only 40 bytes actually available 7. BUG_ON() triggers Fix this by recalculating i_inline_size via ext4_find_inline_data_nolock() immediately after acquiring xattr_sem. This ensures ext4_update_inline_data() and ext4_create_inline_data() work with current values that are protected from concurrent modifications. This is similar to commit a54c4613dac1 ("ext4: fix race writing to an inline_data file while its xattrs are changing") which fixed i_inline_off staleness. This patch addresses the related i_inline_size staleness issue.

[PATCH OLK-6.6] ftrace: Fix softlockup in ftrace_module_enable
by Tengda Wu 22 Dec '25

22 Dec '25

From: Vladimir Riabchun <ferr.lambarginio(a)gmail.com> stable inclusion from stable-v6.6.119 commit e81e6d6d99b16dae11adbeda5c996317942a940c category: bugfix bugzilla: http://atomgit.com/src-openeuler/kernel/issues/11609 CVE: CVE-2025-68173 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 4099b98203d6b33d990586542fa5beee408032a3 ] A soft lockup was observed when loading amdgpu module. If a module has a lot of tracable functions, multiple calls to kallsyms_lookup can spend too much time in RCU critical section and with disabled preemption, causing kernel panic.

[PATCH OLK-6.6] timers: Fix NULL function pointer race in timer_shutdown_sync()

From: Yipeng Zou <zouyipeng(a)huawei.com> stable inclusion from stable-v6.6.118 commit 6665fbd7730b26d770c232b20d1b907e6a67a914 category: bugfix bugzilla: https://gitcode.com/src-openeuler/kernel/issues/11566 CVE: CVE-2025-68214 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 20739af07383e6eb1ec59dcd70b72ebfa9ac362c upstream. There is a race condition between timer_shutdown_sync() and timer expiration that can lead to hitting a WARN_ON in expire_timers(). The issue occurs when timer_shutdown_sync() clears the timer function to NULL while the timer is still running on another CPU. The race scenario looks like this: CPU0 CPU1 <SOFTIRQ> lock_timer_base() expire_timers() base->running_timer = timer; unlock_timer_base() [call_timer_fn enter] mod_timer() ... timer_shutdown_sync() lock_timer_base() // For now, will not detach the timer but only clear its function to NULL if (base->running_timer != timer) ret = detach_if_pending(timer, base, true); if (shutdown) timer->function = NULL; unlock_timer_base() [call_timer_fn exit] lock_timer_base() base->running_timer = NULL; unlock_timer_base() ... // Now timer is pending while its function set to NULL. // next timer trigger <SOFTIRQ> expire_timers() WARN_ON_ONCE(!fn) // hit ... lock_timer_base() // Now timer will detach if (base->running_timer != timer) ret = detach_if_pending(timer, base, true); if (shutdown) timer->function = NULL; unlock_timer_base() The problem is that timer_shutdown_sync() clears the timer function regardless of whether the timer is currently running. This can leave a pending timer with a NULL function pointer, which triggers the WARN_ON_ONCE(!fn) check in expire_timers(). Fix this by only clearing the timer function when actually detaching the timer. If the timer is running, leave the function pointer intact, which is safe because the timer will be properly detached when it finishes running.

[PATCH OLK-5.10] x86/fpu: Ensure XFD state on signal delivery

From: "Chang S.

Sean reported [1] the following splat when running KVM tests: WARNING: CPU: 232 PID: 15391 at xfd_validate_state+0x65/0x70 Call Trace: <TASK> fpu__clear_user_states+0x9c/0x100 arch_do_signal_or_restart+0x142/0x210 exit_to_user_mode_loop+0x55/0x100 do_syscall_64+0x205/0x2c0 entry_SYSCALL_64_after_hwframe+0x4b/0x53 Chao further identified [2] a reproducible scenario involving signal delivery: a non-AMX task is preempted by an AMX-enabled task which modifies the XFD MSR. When the non-AMX task resumes and reloads XSTATE with init values, a warning is triggered due to a mismatch between fpstate::xfd and the CPU's current XFD state. fpu__clear_user_states() does not currently re-synchronize the XFD state after such preemption. Invoke xfd_update_state() which detects and corrects the mismatch if there is a dynamic feature. This also benefits the sigreturn path, as fpu__restore_sig() may call fpu__clear_user_states() when the sigframe is inaccessible.

[PATCH OLK-6.6] erofs: avoid infinite loops due to corrupted subpage compact indexes
by Zizhi Wo 20 Dec '25

20 Dec '25

From: Gao Xiang <hsiangkao(a)linux.alibaba.com> stable inclusion from stable-v6.17.6 commit 8675447a8794983f2b7e694b378112772c17635e category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IDDF3Q CVE: CVE-2025-68251 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit e13d315ae077bb7c3c6027cc292401bc0f4ec683 ] Robert reported an infinite loop observed by two crafted images. The root cause is that `clusterofs` can be larger than `lclustersize` for !NONHEAD `lclusters` in corrupted subpage compact indexes, e.g.: blocksize = lclustersize = 512 lcn = 6 clusterofs = 515 Move the corresponding check for full compress indexes to `z_erofs_load_lcluster_from_disk()` to also cover subpage compact compress indexes. It also fixes the position of `m->type >= Z_EROFS_LCLUSTER_TYPE_MAX` check, since it should be placed right after `z_erofs_load_{compact,full}_lcluster()`. Fixes: 8d2517aaeea3 ("erofs: fix up compacted indexes for block size < 4096") Fixes: 1a5223c182fd ("erofs: do sanity check on m->type in z_erofs_load_compact_lcluster()") Reported-by: Robert Morris <rtm(a)csail.mit.edu> Closes: https://lore.kernel.org/r/35167.1760645886@localhost Reviewed-by: Hongbo Li <lihongbo22(a)huawei.com> Signed-off-by: Gao Xiang <hsiangkao(a)linux.alibaba.com> Signed-off-by: Sasha Levin <sashal(a)kernel.org> Conflicts: fs/erofs/zmap.c [1. z_erofs_load_full_lcluster() function conflicts due to commit: d69189428d50 ("erofs: clean up z_erofs_load_full_lcluster()"); 2. z_erofs_load_lcluster_from_disk() function conflicts due to commit: 1a5223c182fd ("erofs: do sanity check on m->type in z_erofs_load_compact_lcluster()"); 3.

[PATCH OLK-5.10] net: atlantic: fix fragment overflow handling in RX path
by Fanhua Li 19 Dec '25

19 Dec '25

From: Jiefeng Zhang <jiefeng.z.zhang(a)gmail.com> stable inclusion from stable-v5.10.247 commit 34147477eeab24077fcfe9649e282849347d760c category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IDDF5H CVE: CVE-2025-68301 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 5ffcb7b890f61541201461580bb6622ace405aec ] The atlantic driver can receive packets with more than MAX_SKB_FRAGS (17) fragments when handling large multi-descriptor packets. This causes an out-of-bounds write in skb_add_rx_frag_netmem() leading to kernel panic. The issue occurs because the driver doesn't check the total number of fragments before calling skb_add_rx_frag(). When a packet requires more than MAX_SKB_FRAGS fragments, the fragment index exceeds the array bounds. Fix by assuming there will be an extra frag if buff->len > AQ_CFG_RX_HDR_SIZE, then all fragments are accounted for. And reusing the existing check to prevent the overflow earlier in the code path. This crash occurred in production with an Aquantia AQC113 10G NIC. Stack trace from production environment: ``` RIP: 0010:skb_add_rx_frag_netmem+0x29/0xd0 Code: 90 f3 0f 1e fa 0f 1f 44 00 00 48 89 f8 41 89 ca 48 89 d7 48 63 ce 8b 90 c0 00 00 00 48 c1 e1 04 48 01 ca 48 03 90 c8 00 00 00 <48> 89 7a 30 44 89 52 3c 44 89 42 38 40 f6 c7 01 75 74 48 89 fa 83 RSP: 0018:ffffa9bec02a8d50 EFLAGS: 00010287 RAX: ffff925b22e80a00 RBX: ffff925ad38d2700 RCX: fffffffe0a0c8000 RDX: ffff9258ea95bac0 RSI: ffff925ae0a0c800 RDI: 0000000000037a40 RBP: 0000000000000024 R08: 0000000000000000 R09: 0000000000000021 R10: 0000000000000848 R11: 0000000000000000 R12: ffffa9bec02a8e24 R13: ffff925ad8615570 R14: 0000000000000000 R15: ffff925b22e80a00 FS: 0000000000000000(0000) GS:ffff925e47880000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: ffff9258ea95baf0 CR3: 0000000166022004 CR4: 0000000000f72ef0 PKRU: 55555554 Call Trace: <IRQ> aq_ring_rx_clean+0x175/0xe60 [atlantic] ? aq_ring_rx_clean+0x14d/0xe60 [atlantic] ? aq_ring_tx_clean+0xdf/0x190 [atlantic] ? kmem_cache_free+0x348/0x450 ? aq_vec_poll+0x81/0x1d0 [atlantic] ? __napi_poll+0x28/0x1c0 ? net_rx_action+0x337/0x420 ``` Fixes: 6aecbba12b5c ("net: atlantic: add check for MAX_SKB_FRAGS") Changes in v4: - Add Fixes: tag to satisfy patch validation requirements.

[PATCH OLK-5.10] locking/rwsem: Optimize down_read_trylock() under highly contended case
by Tengda Wu 18 Dec '25

18 Dec '25

From: Muchun Song <songmuchun(a)bytedance.com> mainline inclusion from mainline-v5.16-rc3 commit 14c24048841151548a3f4d9e218510c844c1b737 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IDE51T Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- We found that a process with 10 thousnads threads has been encountered a regression problem from Linux-v4.14 to Linux-v5.4. It is a kind of workload which will concurrently allocate lots of memory in different threads sometimes. In this case, we will see the down_read_trylock() with a high hotspot. Therefore, we suppose that rwsem has a regression at least since Linux-v5.4. In order to easily debug this problem, we write a simply benchmark to create the similar situation lile the following. ```c++ #include <sys/mman.h> #include <sys/time.h> #include <sys/resource.h> #include <sched.h> #include <cstdio> #include <cassert> #include <thread> #include <vector> #include <chrono> volatile int mutex; void trigger(int cpu, char* ptr, std::size_t sz) { cpu_set_t set; CPU_ZERO(&set); CPU_SET(cpu, &set); assert(pthread_setaffinity_np(pthread_self(), sizeof(set), &set) == 0); while (mutex); for (std::size_t i = 0; i < sz; i += 4096) { *ptr = '\0'; ptr += 4096; } } int main(int argc, char* argv[]) { std::size_t sz = 100; if (argc > 1) sz = atoi(argv[1]); auto nproc = std::thread::hardware_concurrency(); std::vector<std::thread> thr; sz <<= 30; auto* ptr = mmap(nullptr, sz, PROT_READ | PROT_WRITE, MAP_ANON | MAP_PRIVATE, -1, 0); assert(ptr != MAP_FAILED); char* cptr = static_cast<char*>(ptr); auto run = sz / nproc; run = (run >> 12) << 12; mutex = 1; for (auto i = 0U; i < nproc; ++i) { thr.emplace_back(std::thread([i, cptr, run]() { trigger(i, cptr, run); })); cptr += run; } rusage usage_start; getrusage(RUSAGE_SELF, &usage_start); auto start = std::chrono::system_clock::now(); mutex = 0; for (auto& t : thr) t.join(); rusage usage_end; getrusage(RUSAGE_SELF, &usage_end); auto end = std::chrono::system_clock::now(); timeval utime; timeval stime; timersub(&usage_end.ru_utime, &usage_start.ru_utime, &utime); timersub(&usage_end.ru_stime, &usage_start.ru_stime, &stime); printf("usr: %ld.%06ld\n", utime.tv_sec, utime.tv_usec); printf("sys: %ld.%06ld\n", stime.tv_sec, stime.tv_usec); printf("real: %lu\n", std::chrono::duration_cast<std::chrono::milliseconds>(end - start).count()); return 0; } ``` The functionality of above program is simply which creates `nproc` threads and each of them are trying to touch memory (trigger page fault) on different CPU. Then we will see the similar profile by `perf top`. 25.55% [kernel] [k] down_read_trylock 14.78% [kernel] [k] handle_mm_fault 13.45% [kernel] [k] up_read 8.61% [kernel] [k] clear_page_erms 3.89% [kernel] [k] __do_page_fault The highest hot instruction, which accounts for about 92%, in down_read_trylock() is cmpxchg like the following. 91.89 │ lock cmpxchg %rdx,(%rdi) Sice the problem is found by migrating from Linux-v4.14 to Linux-v5.4, so we easily found that the commit ddb20d1d3aed ("locking/rwsem: Optimize down_read_trylock()") caused the regression. The reason is that the commit assumes the rwsem is not contended at all. But it is not always true for mmap lock which could be contended with thousands threads. So most threads almost need to run at least 2 times of "cmpxchg" to acquire the lock. The overhead of atomic operation is higher than non-atomic instructions, which caused the regression. By using the above benchmark, the real executing time on a x86-64 system before and after the patch were: Before Patch After Patch # of Threads real real reduced by ------------ ------ ------ ---------- 1 65,373 65,206 ~0.0% 4 15,467 15,378 ~0.5% 40 6,214 5,528 ~11.0% For the uncontended case, the new down_read_trylock() is the same as before. For the contended cases, the new down_read_trylock() is faster than before. The more contended, the more fast.

[PATCH OLK-6.6] timers: Fix NULL function pointer race in timer_shutdown_sync()
by Jinjie Ruan 18 Dec '25

18 Dec '25

From: Yipeng Zou <zouyipeng(a)huawei.com> stable inclusion from stable-v6.6.118 commit 6665fbd7730b26d770c232b20d1b907e6a67a914 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IDDEZ3 CVE: CVE-2025-68214 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 20739af07383e6eb1ec59dcd70b72ebfa9ac362c upstream. There is a race condition between timer_shutdown_sync() and timer expiration that can lead to hitting a WARN_ON in expire_timers(). The issue occurs when timer_shutdown_sync() clears the timer function to NULL while the timer is still running on another CPU. The race scenario looks like this: CPU0 CPU1 <SOFTIRQ> lock_timer_base() expire_timers() base->running_timer = timer; unlock_timer_base() [call_timer_fn enter] mod_timer() ... timer_shutdown_sync() lock_timer_base() // For now, will not detach the timer but only clear its function to NULL if (base->running_timer != timer) ret = detach_if_pending(timer, base, true); if (shutdown) timer->function = NULL; unlock_timer_base() [call_timer_fn exit] lock_timer_base() base->running_timer = NULL; unlock_timer_base() ... // Now timer is pending while its function set to NULL. // next timer trigger <SOFTIRQ> expire_timers() WARN_ON_ONCE(!fn) // hit ... lock_timer_base() // Now timer will detach if (base->running_timer != timer) ret = detach_if_pending(timer, base, true); if (shutdown) timer->function = NULL; unlock_timer_base() The problem is that timer_shutdown_sync() clears the timer function regardless of whether the timer is currently running. This can leave a pending timer with a NULL function pointer, which triggers the WARN_ON_ONCE(!fn) check in expire_timers(). Fix this by only clearing the timer function when actually detaching the timer. If the timer is running, leave the function pointer intact, which is safe because the timer will be properly detached when it finishes running.

[PATCH OLK-6.6] usb: storage: Fix memory leak in USB bulk transport
by Li Lingfeng 18 Dec '25

18 Dec '25

From: Desnes Nunes <desnesn(a)redhat.com> stable inclusion from stable-v6.6.119 commit cb1401b5bcc2feb5b038fc4b512e5968b016e05e category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IDDF46 CVE: CVE-2025-68288 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 41e99fe2005182139b1058db71f0d241f8f0078c upstream. A kernel memory leak was identified by the 'ioctl_sg01' test from Linux Test Project (LTP). The following bytes were mainly observed: 0x53425355. When USB storage devices incorrectly skip the data phase with status data, the code extracts/validates the CSW from the sg buffer, but fails to clear it afterwards. This leaves status protocol data in srb's transfer buffer, such as the US_BULK_CS_SIGN 'USBS' signature observed here. Thus, this can lead to USB protocols leaks to user space through SCSI generic (/dev/sg*) interfaces, such as the one seen here when the LTP test requested 512 KiB. Fix the leak by zeroing the CSW data in srb's transfer buffer immediately after the validation of devices that skip data phase. Note: Differently from CVE-2018-1000204, which fixed a big leak by zero- ing pages at allocation time, this leak occurs after allocation, when USB protocol data is written to already-allocated sg pages.

A kernel memory leak was identified by the 'ioctl_sg01' test from Linux Test Project (LTP). The following bytes were mainly observed: 0x53425355. When USB storage devices incorrectly skip the data phase with status data, the code extracts/validates the CSW from the sg buffer, but fails to clear it afterwards. This leaves status protocol data in srb's transfer buffer, such as the US_BULK_CS_SIGN 'USBS' signature observed here. Thus, this can lead to USB protocols leaks to user space through SCSI generic (/dev/sg*) interfaces, such as the one seen here when the LTP test requested 512 KiB. Fix the leak by zeroing the CSW data in srb's transfer buffer immediately after the validation of devices that skip data phase. Note: Differently from CVE-2018-1000204, which fixed a big leak by zero- ing pages at allocation time, this leak occurs after allocation, when USB protocol data is written to already-allocated sg pages.

[PATCH openEuler-1.0-LTS] mm/mem_reliable: use percise count during limit check
by Wupeng Ma 18 Dec '25

18 Dec '25

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8USBA -------------------------------- If the fallback for memory reliable is enabled, direct reclaim will be used if the task's reliable memory limit is reached and pages need to be released. However, percpu_counter_read_positive() provides a fast but imprecise counter reading. During limit enforcement, this inaccuracy may cause the observed usage to appear significantly larger than the actual value. As a result, even repeated constrained reclaim attempts may fail to bring memory usage below the limit, eventually leading to OOM. To avoid this issue, use an accurate counter check when determining whether the reliable memory limit has been exceeded.

[PATCH OLK-5.10] nvme: nvme-fc: Ensure ->ioerr_work is cancelled in nvme_fc_delete_ctrl()

From: "Ewan D. Milne" <emilne(a)redhat.com> stable inclusion from stable-v5.10.247 commit 3d78e8e01251da032a5f7cbc9728e4ab1a5a5464 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IDATPF CVE: CVE-2025-40261 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 0a2c5495b6d1ecb0fa18ef6631450f391a888256 upstream. nvme_fc_delete_assocation() waits for pending I/O to complete before returning, and an error can cause ->ioerr_work to be queued after cancel_work_sync() had been called. Move the call to cancel_work_sync() to be after nvme_fc_delete_association() to ensure ->ioerr_work is not running when the nvme_fc_ctrl object is freed.

[PATCH OLK-6.6] usb: storage: sddr55: Reject out-of-bound new_pba

17 Dec '25

From: Tianchu Chen <flynnnchen(a)tencent.com> stable inclusion from stable-v6.6.119 commit 04a8a6393f3f2f471e05eacca33282dd30b01432 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IDCQJA CVE: CVE-2025-40345 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ---------------------------------------------------------------------- commit b59d4fda7e7d0aff1043a7f742487cb829f5aac1 upstream. Discovered by Atuin - Automated Vulnerability Discovery Engine. new_pba comes from the status packet returned after each write. A bogus device could report values beyond the block count derived from info->capacity, letting the driver walk off the end of pba_to_lba[] and corrupt heap memory. Reject PBAs that exceed the computed block count and fail the transfer so we avoid touching out-of-range mapping entries.

[PATCH OLK-6.6] arm64/mpam: Synchronize MPAM Partid to kernel mode
by Zeng Heng 17 Dec '25

17 Dec '25

hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IDD55N -------------------------------- Currently, the MPAM implementation on Linux only applies isolation control to tasks' user-space, while resource allocation for execution in kernel mode is according to the root group's (Partid=0) policy. With MPAM adding L2 cache support, and given small L2 capacity, frequently switching partition policies between kernel and user space would cause L2 thrashing and degrade performance. Moreover, to support MPAM isolation for kernel-space processes, kernel space should adopt the same partition policy as user space.

[PATCH openEuler-1.0-LTS v2 0/2] xfs: fix stale imap reuse during page writeback
by Long Li 16 Dec '25

16 Dec '25

During page write-back operations, a copy of the imap is stored in wpc->imap. Even if the file's imap mapping changes during this process, the subsequent operations continue to reuse wpc->imap, causing data to be written to incorrect blocks that are not mapped to that file.

[PATCH OLK-6.6] i40e: remove read access to debugfs files
by Wang Liang 16 Dec '25

16 Dec '25

From: Jacob Keller <jacob.e.keller(a)intel.com> mainline inclusion from mainline-v6.17-rc5 commit 9fcdb1c3c4ba134434694c001dbff343f1ffa319 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ID0R34 CVE: CVE-2025-39901 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The 'command' and 'netdev_ops' debugfs files are a legacy debugging interface supported by the i40e driver since its early days by commit 02e9c290814c ("i40e: debugfs interface"). Both of these debugfs files provide a read handler which is mostly useless, and which is implemented with questionable logic. They both use a static 256 byte buffer which is initialized to the empty string. In the case of the 'command' file this buffer is literally never used and simply wastes space. In the case of the 'netdev_ops' file, the last command written is saved here. On read, the files contents are presented as the name of the device followed by a colon and then the contents of their respective static buffer. For 'command' this will always be "<device>: ". For 'netdev_ops', this will be "<device>: <last command written>". But note the buffer is shared between all devices operated by this module. At best, it is mostly meaningless information, and at worse it could be accessed simultaneously as there doesn't appear to be any locking mechanism. We have also recently received multiple reports for both read functions about their use of snprintf and potential overflow that could result in reading arbitrary kernel memory. For the 'command' file, this is definitely impossible, since the static buffer is always zero and never written to. For the 'netdev_ops' file, it does appear to be possible, if the user carefully crafts the command input, it will be copied into the buffer, which could be large enough to cause snprintf to truncate, which then causes the copy_to_user to read beyond the length of the buffer allocated by kzalloc. A minimal fix would be to replace snprintf() with scnprintf() which would cap the return to the number of bytes written, preventing an overflow. A more involved fix would be to drop the mostly useless static buffers, saving 512 bytes and modifying the read functions to stop needing those as input. Instead, lets just completely drop the read access to these files. These are debug interfaces exposed as part of debugfs, and I don't believe that dropping read access will break any script, as the provided output is pretty useless. You can find the netdev name through other more standard interfaces, and the 'netdev_ops' interface can easily result in garbage if you issue simultaneous writes to multiple devices at once. In order to properly remove the i40e_dbg_netdev_ops_buf, we need to refactor its write function to avoid using the static buffer. Instead, use the same logic as the i40e_dbg_command_write, with an allocated buffer. Update the code to use this instead of the static buffer, and ensure we free the buffer on exit. This fixes simultaneous writes to 'netdev_ops' on multiple devices, and allows us to remove the now unused static buffer along with removing the read access.

From: "Russell King (Oracle)" <rmk+kernel(a)armlinux.org.uk> mainline inclusion from mainline-v6.19-rc1 commit 40b466db1dffb41f0529035c59c5739636d0e5b8 category: other bugzilla: https://gitee.com/openeuler/kernel/issues/IDD7MD Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Allow __do_kernel_fault() to detect the execution of memory, so we can provide the same fault message as do_page_fault() would do.

[PATCH OLK-6.6] arm64/mpam: Synchronize MPAM Partid to kernel mode
by Zeng Heng 15 Dec '25

15 Dec '25

hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IDD55N -------------------------------- Currently, the MPAM implementation on Linux only applies isolation control to tasks' user-space, while resource allocation for execution in kernel mode is according to the root group's (Partid=0) policy. With MPAM adding L2 cache support, and given small L2 capacity, frequently switching partition policies between kernel and user space would cause L2 thrashing and degrade performance. Moreover, to support MPAM isolation for kernel-space processes, kernel space should adopt the same partition policy as user space. To ensure the Partid state is updated promptly after the CPU exits from low power mode, add wmb() barrier in the CPU_PM_EXIT flow to guarantee that.

[PATCH OLK-6.6] xsched: prevent linked list corruption in RT priority updates

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IDB5TR ----------------------------------------- Add scheduling class validation in xsched_rt_prio_set() to ensure only RT-scheduled tasks can perform RT priority modifications.

[PATCH OLK-6.6] mm: migrate: add dma copy offloading for hugetlb
by Zeng Heng 15 Dec '25

15 Dec '25

From: Tong Tiangen <tongtiangen(a)huawei.com> hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IDBGTZ CVE: NA ------------------------------- Large memory migration imposes significant overhead on the CPU. This patch introduces enhancements to the page migration by offloading the copy to UDMA hardware which based on the DMA engine framework, and a new migration mode has been introduced, If DMA migration fails, it will fall back to CPU migration. DMA migration supports both asynchronous and synchronous modes for subsequent debugging purposes.
