In the Linux kernel, the following vulnerability has been resolved: drm/amd/pm: bound pp_dpm_set_pp_table() memcpy The powerplay path allocates hardcode_pp_table once with kmemdup(..., soft_pp_table_size). memcpy(..., size) used the sysfs store count (up to PAGE_SIZE) with no upper bound, causing heap overflow. Reject writes where size exceeds soft_pp_table_size.

An update of the linux package has been released.

  - In the Linux kernel, the following vulnerability has been resolved: crypto: essiv - Handle EBUSY correctly     As it is essiv only handles the special return value of EINPROGERSS, which means that in all other cases     it will free data related to the request. However, as the caller of essiv may specify MAY_BACKLOG, we also     need to expect EBUSY and treat it in the same way. Otherwise backlogged requests will trigger a use-after-     free.

  - In the Linux kernel, the following vulnerability has been resolved: net: avoid potential underflow in     qdisc_pkt_len_init() with UFO After commit 7c6d2ecbda83 (net: be more gentle about silly gso requests     coming from user) virtio_net_hdr_to_skb() had sanity check to detect malicious attempts from user space     to cook a bad GSO packet. Then commit cf9acc90c80ec (net: virtio_net_hdr_to_skb: count transport header     in UFO) while fixing one issue, allowed user space to cook a GSO packet with the following characteristic     : IPv4 SKB_GSO_UDP, gso_size=3, skb->len = 28. When this packet arrives in qdisc_pkt_len_init(), we end up     with hdr_len = 28 (IPv4 header + UDP header), matching skb->len Then the following sets gso_segs to 0 :
    gso_segs = DIV_ROUND_UP(skb->len - hdr_len, shinfo->gso_size); Then later we set     qdisc_skb_cb(skb)->pkt_len to back to zero :/ qdisc_skb_cb(skb)->pkt_len += (gso_segs - 1) * hdr_len; This     leads to the following crash in fq_codel [1] qdisc_pkt_len_init() is best effort, we only want an     estimation of the bytes sent on the wire, not crashing the kernel. This patch is fixing this particular     issue, a following one adds more sanity checks for another potential bug.

The Rocky Linux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1792762308 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: scsi: mpi3mr: Synchronous access b/w     reset and tm thread for reply queue When the task management thread processes reply queues while the reset     thread resets them, the task management thread accesses an invalid queue ID (0xFFFF), set by the reset     thread, which points to unallocated memory, causing a crash. Add flag 'io_admin_reset_sync' to synchronize     access between the reset, I/O, and admin threads. Before a reset, the reset handler sets this flag to     block I/O and admin processing threads. If any thread bypasses the initial check, the reset thread waits     up to 10 seconds for processing to finish. If the wait exceeds 10 seconds, the controller is marked as     unrecoverable. (CVE-2025-37861)

  - In the Linux kernel, the following vulnerability has been resolved: Bluetooth: MGMT: cancel mesh send     timer when hdev removed mesh_send_done timer is not canceled when hdev is removed, which causes crash if     the timer triggers after hdev is gone. Cancel the timer when MGMT removes the hdev, like other MGMT     timers. Should fix the BUG: sporadically seen by BlueZ test bot (in Mesh - Send cancel - 1 test). Log:

  - In the Linux kernel, the following vulnerability has been resolved: ASoC: Intel: avs: Disable periods-     elapsed work when closing PCM avs_dai_fe_shutdown() handles the shutdown procedure for HOST HDAudio stream     while period-elapsed work services its IRQs. As the former frees the DAI's private context, these two     operations shall be synchronized to avoid slab-use-after-free or worse errors. (CVE-2025-40344)

  - In the Linux kernel, the following vulnerability has been resolved: ipv6: icmp: clear skb2->cb[] in     ip6_err_gen_icmpv6_unreach() Sashiko AI-review observed: In ip6_err_gen_icmpv6_unreach(), the skb is an     outer IPv4 ICMP error packet where its cb contains an IPv4 inet_skb_parm. When skb is cloned into skb2 and     passed to icmp6_send(), it uses IP6CB(skb2). IP6CB interprets the IPv4 inet_skb_parm as an inet6_skb_parm.
    The cipso offset in inet_skb_parm.opt directly overlaps with dsthao in inet6_skb_parm at offset 18. If an     attacker sends a forged ICMPv4 error with a CIPSO IP option, dsthao would be a non-zero offset. Inside     icmp6_send(), mip6_addr_swap() is called and uses ipv6_find_tlv(skb, opt->dsthao, IPV6_TLV_HAO). This     would scan the inner, attacker-controlled IPv6 packet starting at that offset, potentially returning a     fake TLV without checking if the remaining packet length can hold the full 18-byte struct     ipv6_destopt_hao. Could mip6_addr_swap() then perform a 16-byte swap that extends past the end of the     packet data into skb_shared_info? Should the cb array also be cleared in ip6_err_gen_icmpv6_unreach() and     ip6ip6_err() to prevent this? This patch implements the first suggestion. I am not sure if ip6ip6_err()     needs to be changed. A separate patch would be better anyway. (CVE-2026-43038)

  - In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix double free in     rxe_srq_from_init In rxe_srq_from_init(), the queue pointer 'q' is assigned to 'srq->rq.queue' before     copying the SRQ number to user space. If copy_to_user() fails, the function calls rxe_queue_cleanup() to     free the queue, but leaves the now-invalid pointer in 'srq->rq.queue'. The caller of rxe_srq_from_init()     (rxe_create_srq) eventually calls rxe_srq_cleanup() upon receiving the error, which triggers a second     rxe_queue_cleanup() on the same memory, leading to a double free. The call trace looks like this:
    kmem_cache_free+0x.../0x... rxe_queue_cleanup+0x1a/0x30 [rdma_rxe] rxe_srq_cleanup+0x42/0x60 [rdma_rxe]     rxe_elem_release+0x31/0x70 [rdma_rxe] rxe_create_srq+0x12b/0x1a0 [rdma_rxe] ib_create_srq_user+0x9a/0x150     [ib_core] Fix this by moving 'srq->rq.queue = q' after copy_to_user.

  - In the Linux kernel, the following vulnerability has been resolved: scsi: mpi3mr: Synchronous access b/w     reset and tm thread for reply queue When the task management thread processes reply queues while the reset     thread resets them, the task management thread accesses an invalid queue ID (0xFFFF), set by the reset     thread, which points to unallocated memory, causing a crash. Add flag 'io_admin_reset_sync' to synchronize     access between the reset, I/O, and admin threads. Before a reset, the reset handler sets this flag to     block I/O and admin processing threads. If any thread bypasses the initial check, the reset thread waits     up to 10 seconds for processing to finish. If the wait exceeds 10 seconds, the controller is marked as     unrecoverable. (CVE-2025-37861)

  - In the Linux kernel, the following vulnerability has been resolved: Bluetooth: MGMT: cancel mesh send     timer when hdev removed mesh_send_done timer is not canceled when hdev is removed, which causes crash if     the timer triggers after hdev is gone. Cancel the timer when MGMT removes the hdev, like other MGMT     timers. Should fix the BUG: sporadically seen by BlueZ test bot (in Mesh - Send cancel - 1 test). Log:

  - In the Linux kernel, the following vulnerability has been resolved: ASoC: Intel: avs: Disable periods-     elapsed work when closing PCM avs_dai_fe_shutdown() handles the shutdown procedure for HOST HDAudio stream     while period-elapsed work services its IRQs. As the former frees the DAI's private context, these two     operations shall be synchronized to avoid slab-use-after-free or worse errors. (CVE-2025-40344)

  - In the Linux kernel, the following vulnerability has been resolved: ipv6: icmp: clear skb2->cb[] in     ip6_err_gen_icmpv6_unreach() Sashiko AI-review observed: In ip6_err_gen_icmpv6_unreach(), the skb is an     outer IPv4 ICMP error packet where its cb contains an IPv4 inet_skb_parm. When skb is cloned into skb2 and     passed to icmp6_send(), it uses IP6CB(skb2). IP6CB interprets the IPv4 inet_skb_parm as an inet6_skb_parm.
    The cipso offset in inet_skb_parm.opt directly overlaps with dsthao in inet6_skb_parm at offset 18. If an     attacker sends a forged ICMPv4 error with a CIPSO IP option, dsthao would be a non-zero offset. Inside     icmp6_send(), mip6_addr_swap() is called and uses ipv6_find_tlv(skb, opt->dsthao, IPV6_TLV_HAO). This     would scan the inner, attacker-controlled IPv6 packet starting at that offset, potentially returning a     fake TLV without checking if the remaining packet length can hold the full 18-byte struct     ipv6_destopt_hao. Could mip6_addr_swap() then perform a 16-byte swap that extends past the end of the     packet data into skb_shared_info? Should the cb array also be cleared in ip6_err_gen_icmpv6_unreach() and     ip6ip6_err() to prevent this? This patch implements the first suggestion. I am not sure if ip6ip6_err()     needs to be changed. A separate patch would be better anyway. (CVE-2026-43038)

  - In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix double free in     rxe_srq_from_init In rxe_srq_from_init(), the queue pointer 'q' is assigned to 'srq->rq.queue' before     copying the SRQ number to user space. If copy_to_user() fails, the function calls rxe_queue_cleanup() to     free the queue, but leaves the now-invalid pointer in 'srq->rq.queue'. The caller of rxe_srq_from_init()     (rxe_create_srq) eventually calls rxe_srq_cleanup() upon receiving the error, which triggers a second     rxe_queue_cleanup() on the same memory, leading to a double free. The call trace looks like this:
    kmem_cache_free+0x.../0x... rxe_queue_cleanup+0x1a/0x30 [rdma_rxe] rxe_srq_cleanup+0x42/0x60 [rdma_rxe]     rxe_elem_release+0x31/0x70 [rdma_rxe] rxe_create_srq+0x12b/0x1a0 [rdma_rxe] ib_create_srq_user+0x9a/0x150     [ib_core] Fix this by moving 'srq->rq.queue = q' after copy_to_user.

  - In the Linux kernel, the following vulnerability has been resolved: mm/khugepaged: fix ->anon_vma race If     an ->anon_vma is attached to the VMA, collapse_and_free_pmd() requires it to be locked. Page table     traversal is allowed under any one of the mmap lock, the anon_vma lock (if the VMA is associated with an     anon_vma), and the mapping lock (if the VMA is associated with a mapping); and so to be able to remove     page tables, we must hold all three of them. retract_page_tables() bails out if an ->anon_vma is attached,     but does this check before holding the mmap lock (as the comment above the check explains). If we racily     merged an existing ->anon_vma (shared with a child process) from a neighboring VMA, subsequent rmap     traversals on pages belonging to the child will be able to see the page tables that we are concurrently     removing while assuming that nothing else can access them. Repeat the ->anon_vma check once we hold the     mmap lock to ensure that there really is no concurrent page table access. Hitting this bug causes a     lockdep warning in collapse_and_free_pmd(), in the line     lockdep_assert_held_write(&vma->anon_vma->root->rwsem). It can also lead to use-after-free access.

  - In the Linux kernel, the following vulnerability has been resolved: net: skbuff: propagate shared-frag     marker through frag-transfer helpers Two frag-transfer helpers (__pskb_copy_fclone() and skb_shift()) fail     to propagate the SKBFL_SHARED_FRAG bit in skb_shinfo()->flags when moving frags from source to     destination. __pskb_copy_fclone() defers the rest of the shinfo metadata to skb_copy_header() after     copying frag descriptors, but that helper only carries over gso_{size,segs, type} and never touches     skb_shinfo()->flags; skb_shift() moves frag descriptors directly and leaves flags untouched. As a result,     the destination skb keeps a reference to the same externally-owned or page-cache-backed pages while     reporting skb_has_shared_frag() as false. The mismatch is harmful in any in-place writer that uses     skb_has_shared_frag() to decide whether shared pages must be detoured through skb_cow_data(). ESP input is     one such writer (esp4.c, esp6.c), and a single nft 'dup to <local>' rule -- or any other nf_dup_ipv4() /     xt_TEE caller -- is enough to land a pskb_copy()'d skb in esp_input() with the marker stripped, letting an     unprivileged user write into the page cache of a root-owned read-only file via authencesn-ESN stray     writes. Set SKBFL_SHARED_FRAG on the destination whenever frag descriptors were actually moved from the     source. skb_copy() and skb_copy_expand() share skb_copy_header() too but linearize all paged data into     freshly allocated head storage and emerge with nr_frags == 0, so skb_has_shared_frag() returns false on     its own; they need no change. The same omission exists in skb_gro_receive() and skb_gro_receive_list().
    The former moves the incoming skb's frag descriptors into the accumulator's last sub-skb via two paths (a     direct frag-move loop and the head_frag + memcpy path); the latter chains the incoming skb whole onto p's     frag_list. Downstream skb_segment() reads only skb_shinfo(p)->flags, and skb_segment_list() reuses each     sub-skb's shinfo as the nskb -- both p and lp must carry the marker. The same omission also exists in     tcp_clone_payload(), which builds an MTU probe skb by moving frag descriptors from skbs on sk_write_queue     into a freshly allocated nskb. The helper falls into the same family and warrants the same fix for     consistency; no TCP TX-side in-place writer is currently known to reach a user page through this gap, but     a future consumer depending on the marker would regress silently. The same omission exists in     skb_segment(): the per-iteration flag merge takes only head_skb's flag, and the inner switch that rebinds     frag_skb to list_skb on head_skb-frags exhaustion does not fold the new frag_skb's flag into nskb. Fold     frag_skb's flag at both sites so segments drawing frags from frag_list members carry the marker.

  - In the Linux kernel, the following vulnerability has been resolved: ipv6: Fix signed integer overflow in     l2tp_ip6_sendmsg When len >= INT_MAX - transhdrlen, ulen = len + transhdrlen will be overflow. To fix, we     can follow what udpv6 does and subtract the transhdrlen from the max. (CVE-2022-49727)

  - In the Linux kernel, the following vulnerability has been resolved: bpf: Fix accesses to uninit stack     slots Privileged programs are supposed to be able to read uninitialized stack memory (ever since     6715df8d5) but, before this patch, these accesses were permitted inconsistently. In particular, accesses     were permitted above state->allocated_stack, but not below it. In other words, if the stack was already     large enough, the access was permitted, but otherwise the access was rejected instead of being allowed     to grow the stack. This undesired rejection was happening in two places: - in     check_stack_slot_within_bounds() - in check_stack_range_initialized() This patch arranges for these     accesses to be permitted. A bunch of tests that were relying on the old rejection had to change; all of     them were changed to add also run unprivileged, in which case the old behavior persists. One tests     couldn't be updated - global_func16 - because it can't run unprivileged for other reasons. This patch also     fixes the tracking of the stack size for variable-offset reads. This second fix is bundled in the same     commit as the first one because they're inter-related. Before this patch, writes to the stack using     registers containing a variable offset (as opposed to registers with fixed, known values) were not     properly contributing to the function's needed stack size. As a result, it was possible for a program to     verify, but then to attempt to read out-of-bounds data at runtime because a too small stack had been     allocated for it. Each function tracks the size of the stack it needs in bpf_subprog_info.stack_depth,     which is maintained by update_stack_depth(). For regular memory accesses, check_mem_access() was calling     update_state_depth() but it was passing in only the fixed part of the offset register, ignoring the     variable offset. This was incorrect; the minimum possible value of that register should be used instead.
    This tracking is now fixed by centralizing the tracking of stack size in grow_stack_state(), and by     lifting the calls to grow_stack_state() to check_stack_access_within_bounds() as suggested by Andrii. The     code is now simpler and more convincingly tracks the correct maximum stack size.
    check_stack_range_initialized() can now rely on enough stack having been allocated for the access; this     helps with the fix for the first issue. A few tests were changed to also check the stack depth     computation. The one that fails without this patch is verifier_var_off:stack_write_priv_vs_unpriv.

  - In the Linux kernel, the following vulnerability has been resolved: mm/khugepaged: invoke MMU notifiers in     shmem/file collapse paths Any codepath that zaps page table entries must invoke MMU notifiers to ensure     that secondary MMUs (like KVM) don't keep accessing pages which aren't mapped anymore. Secondary MMUs     don't hold their own references to pages that are mirrored over, so failing to notify them can lead to     page use-after-free. I'm marking this as addressing an issue introduced in commit f3f0e1d2150b     (khugepaged: add support of collapse for tmpfs/shmem pages), but most of the security impact of this     only came in commit 27e1f8273113 (khugepaged: enable collapse pmd for pte-mapped THP), which actually     omitted flushes for the removal of present PTEs, not just for the removal of empty page tables.

This happens because virtnet_freeze() frees the receive_queue completely     (including struct xdp_rxq_info) but does not call xdp_rxq_info_unreg(). Similarly, virtnet_restore() sets     up the receive_queue again but does not call xdp_rxq_info_reg(). Actually, parts of virtnet_freeze_down()     and virtnet_restore_up() are almost identical to virtnet_close() and virtnet_open(): only the calls to     xdp_rxq_info_(un)reg() are missing. This means that we can fix this easily and avoid such problems in the     future by just calling virtnet_close()/open() from the freeze/restore handlers. Aside from adding the     missing xdp_rxq_info calls the only difference is that the refill work is only cancelled if     netif_running(). However, this should not make any functional difference since the refill work should only     be active if the network interface is actually up. (CVE-2022-49687)
