[PATCH v5.10-next] vhost-scsi: protect vq->log_used with vq->mutex
by ZHENG Xinyu 02 Jul '25

02 Jul '25

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. This problem was first found in linux-6.6.y and also exists in the community syzkaller: https://lore.kernel.org/all/000000000000ada39605a5e71711@google.com/T/ Link: https://lkml.kernel.org/r/20250529155650.4017699-1-pulehui@huaweicloud.com Link: https://lkml.kernel.org/r/20250529155650.4017699-2-pulehui@huaweicloud.com Fixes: 2b1444983508 ("uprobes, mm, x86: Add the ability to install and remove uprobes breakpoints") Signed-off-by: Pu Lehui <pulehui(a)huawei.com> Suggested-by: Lorenzo Stoakes <lorenzo.stoakes(a)oracle.com> Reviewed-by: Lorenzo Stoakes <lorenzo.stoakes(a)oracle.com> Acked-by: David Hildenbrand <david(a)redhat.com> Cc: Jann Horn <jannh(a)google.com> Cc: Liam Howlett <liam.howlett(a)oracle.com> Cc: "Masami Hiramatsu (Google)" <mhiramat(a)kernel.org> Cc: Oleg Nesterov <oleg(a)redhat.com> Cc: Peter Zijlstra <peterz(a)infradead.org> Cc: Vlastimil Babka <vbabka(a)suse.cz> Cc: <stable(a)vger.kernel.org> Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> Conflicts: fs/userfaultfd.c include/linux/mm.h mm/madvise.c mm/mempolicy.c mm/mlock.c mm/mmap.c mm/mprotect.c mm/vma.h mm/vma.c [The conflicts were due to refactor commit 440703e082b9c and 2f1c6611b0a8] Signed-off-by: Pu Lehui <pulehui(a)huawei.com> --- fs/userfaultfd.c | 6 +++--- include/linux/mm.h | 6 +++--- mm/madvise.c | 2 +- mm/mempolicy.c | 2 +- mm/mlock.c | 2 +- mm/mmap.c | 46 ++++++++++++++++++++++++++++++++++------------ mm/mprotect.c | 2 +- 7 files changed, 44 insertions(+), 22 deletions(-) diff --git a/fs/userfaultfd.c b/fs/userfaultfd.c index 803c61f66d54..3e11e9763527 100644 --- a/fs/userfaultfd.c +++ b/fs/userfaultfd.c @@ -925,7 +925,7 @@ static int userfaultfd_release(struct inode *inode, struct file *file) new_flags, vma->anon_vma, vma->vm_file, vma->vm_pgoff, vma_policy(vma), - NULL_VM_UFFD_CTX);

[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.

Instead of changing '>' to '>=' there, add the bounds check at the start of the second 'case' (the first one already has it). Also, remove redundant last checks for 'j' index bigger than array size. The expression is always false. Moreover, before or after the patch 'table->last' can be equal to SMC_NISLANDS_MC_REGISTER_ARRAY_SIZE and it seems it can be a valid value.

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().

[PATCH OLK-5.10] nvme-tcp: fix potential memory corruption in nvme_tcp_recv_pdu()

[PATCH OLK-6.6 v2] mempolicy: optimize queue_folios_pte_range by PTE batching

[PATCH OLK-5.10,V2] nvme-tcp: fix potential memory corruption in nvme_tcp_recv_pdu()

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.
