In the Linux kernel, the following vulnerability has been resolved: dmaengine: wait for RCU readers before releasing dma_device dma_issue_pending_all() walks the dma_device_list with list_for_each_entry_rcu() under rcu_read_lock(). dma_device_release() unlinks the device with list_del_rcu() and then calls device->device_release() (which in many drivers, such as plx_dma.c, directly calls kfree()). Because there is no grace period between unlinking the device and freeing it, concurrent RCU readers in dma_issue_pending_all() can access the device after it has been freed. The lockless walk originally relied on clients holding a dmaengine reference to pin the provider module, and therefore the device, for as long as they might traverse the list. Commit 8ad342a86359 ("dmaengine: Add reference counting to dma_device struct") decoupled the dma_device lifetime from the module reference, so the device can now be released while a reader is still walking the list. Add synchronize_rcu() before the device is freed, so RCU readers are guaranteed to have finished. Keep it unconditional: providers that do not implement device_release() free the device themselves once dma_async_device_unregister() returns. This call will delay for a grace period with dma_list_mutex held, which is safe and only teardown path is delayed.

  - In the Linux kernel, the following vulnerability has been resolved: net: bridge: fix vlan tunnel dst     refcnt when egressing The egress tunnel code uses dst_clone() and directly sets the result which is wrong     because the entry might have 0 refcnt or be already deleted, causing number of problems. It also triggers     the WARN_ON() in dst_hold()[1] when a refcnt couldn't be taken. Fix it by using dst_hold_safe() and     checking if a reference was actually taken before setting the dst.

  - In the Linux kernel, the following vulnerability has been resolved: net: bridge: fix vlan tunnel dst null     pointer dereference This patch fixes a tunnel_dst null pointer dereference due to lockless access in the     tunnel egress path. When deleting a vlan tunnel the tunnel_dst pointer is set to NULL without waiting a     grace period (i.e. while it's still usable) and packets egressing are dereferencing it without checking.
    Use READ/WRITE_ONCE to annotate the lockless use of tunnel_id, use RCU for accessing tunnel_dst and make     sure it is read only once and checked in the egress path. The dst is already properly RCU protected so we     don't need to do anything fancy than to make sure tunnel_id and tunnel_dst are read only once and checked     in the egress path. (CVE-2021-47223)

  - In the Linux kernel, the following vulnerability has been resolved: bpf: Guard stack limits against 32bit     overflow This patch promotes the arithmetic around checking stack bounds to be done in the 64-bit domain,     instead of the current 32bit. The arithmetic implies adding together a 64-bit register with a int offset.
    The register was checked to be below 1<<29 when it was variable, but not when it was fixed. The offset     either comes from an instruction (in which case it is 16 bit), from another register (in which case the     caller checked it to be below 1<<29 [1]), or from the size of an argument to a kfunc (in which case it can     be a u32 [2]). Between the register being inconsistently checked to be below 1<<29, and the offset being     up to an u32, it appears that we were open to overflowing the `int`s which were currently used for     arithmetic.

Note that the exiting session will stay in server->smb_ses_list until it     complete the cifs_free_ipc() and logoff() and then delete itself from the list. (CVE-2023-53794)

  - 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: RDMA/uverbs: Validate wqe_size before     using it in ib_uverbs_post_send ib_uverbs_post_send() uses cmd.wqe_size from userspace without any     validation before passing it to kmalloc() and using the allocated buffer as struct ib_uverbs_send_wr. If a     user provides a small wqe_size value (e.g., 1), kmalloc() will succeed, but subsequent accesses to     user_wr->opcode, user_wr->num_sge, and other fields will read beyond the allocated buffer, resulting in an     out-of-bounds read from kernel heap memory. This could potentially leak sensitive kernel information to     userspace. Additionally, providing an excessively large wqe_size can trigger a WARNING in the memory     allocation path, as reported by syzkaller. This is inconsistent with ib_uverbs_unmarshall_recv() which     properly validates that wqe_size >= sizeof(struct ib_uverbs_recv_wr) before proceeding. Add the same     validation for ib_uverbs_post_send() to ensure wqe_size is at least sizeof(struct ib_uverbs_send_wr).
    (CVE-2026-45856)

  - In the Linux kernel, the following vulnerability has been resolved: crypto: authencesn - reject short     ahash digests during instance creation authencesn requires either a zero authsize or an authsize of at     least 4 bytes because the ESN encrypt/decrypt paths always move 4 bytes of high-order sequence number data     at the end of the authenticated data. While crypto_authenc_esn_setauthsize() already rejects explicit non-     zero authsizes in the range 1..3, crypto_authenc_esn_create() still copied auth->digestsize into     inst->alg.maxauthsize without validating it. The AEAD core then initialized the tfm's default authsize     from that value. As a result, selecting an ahash with digest size 1..3, such as cbcmac(cipher_null),     exposed authencesn instances whose default authsize was invalid even though setauthsize() would have     rejected the same value. AF_ALG could then trigger the ESN tail handling with a too-short tag and hit an     out-of-bounds access. Reject authencesn instances whose ahash digest size is in the invalid non-zero range     1..3 so that no tfm can inherit an unsupported default authsize. (CVE-2026-46033)

  - In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Validate pad and ICRC before     payload_size() in rxe_rcv rxe_rcv() currently checks only that the incoming packet is at least     header_size(pkt) bytes long before payload_size() is used. However, payload_size() subtracts both the     attacker-controlled BTH pad field and RXE_ICRC_SIZE from pkt->paylen: payload_size = pkt->paylen -     offset[RXE_PAYLOAD] - bth_pad(pkt) - RXE_ICRC_SIZE This means a short packet can still make payload_size()     underflow even if it includes enough bytes for the fixed headers. Simply requiring header_size(pkt) +     RXE_ICRC_SIZE is not sufficient either, because a packet with a forged non-zero BTH pad can still leave     payload_size() negative and pass an underflowed value to later receive-path users. Fix this by validating     pkt->paylen against the full minimum length required by payload_size(): header_size(pkt) + bth_pad(pkt) +     RXE_ICRC_SIZE. (CVE-2026-46043)

The CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS7:CLSA-2026:1792234299 advisory.

  - nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote     attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte     nfta_payload attribute, an skb_pull can encounter a negative skb->len. (CVE-2022-36946)

  - In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: Fix a memory     corruption issue A few lines above, space is kzalloc()'ed for: sizeof(struct iwl_nvm_data) + sizeof(struct     ieee80211_channel) + sizeof(struct ieee80211_rate) 'mvm->nvm_data' is a 'struct iwl_nvm_data', so it is     fine. At the end of this structure, there is the 'channels' flex array. Each element is of type 'struct     ieee80211_channel'. So only 1 element is allocated in this array. When doing:
    mvm->nvm_data->bands[0].channels = mvm->nvm_data->channels; We point at the first element of the     'channels' flex array. So this is fine. However, when doing: mvm->nvm_data->bands[0].bitrates = (void
    *)((u8 *)mvm->nvm_data->channels + 1); because of the (u8 *) cast, we add only 1 to the address of the     beginning of the flex array. It is likely that we want point at the 'struct ieee80211_rate' allocated just     after. Remove the spurious casting so that the pointer arithmetic works as expected. (CVE-2023-52531)

  - In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Don't (re)check L1     intercepts when completing userspace I/O When completing emulation of instruction that generated a     userspace exit for I/O, don't recheck L1 intercepts as KVM has already finished that phase of instruction     execution, i.e. has already committed to allowing L2 to perform I/O. If L1 (or host userspace) modifies     the I/O permission bitmaps during the exit to userspace, KVM will treat the access as being intercepted     despite already having emulated the I/O access. Pivot on EMULTYPE_NO_DECODE to detect that KVM is     completing emulation. Of the three users of EMULTYPE_NO_DECODE, only complete_emulated_io() (the intended     recipient) can reach the code in question. gp_interception()'s use is mutually exclusive with     is_guest_mode(), and complete_emulated_insn_gp() unconditionally pairs EMULTYPE_NO_DECODE with     EMULTYPE_SKIP. The bad behavior was detected by a syzkaller program that toggles port I/O interception     during the userspace I/O exit, ultimately resulting in a WARN on vcpu->arch.pio.count being non-zero due     to KVM no completing emulation of the I/O instruction.

  - In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btusb: fix use-after-free     on registration failure Make sure to release the sibling interfaces in case controller registration fails     to avoid use-after-free and double-free when they are eventually disconnected. This issue was reported by     Sashiko while reviewing a fix for a wakeup source leak in the btusb probe errors paths. (CVE-2026-64471)

  - In the Linux kernel, the following vulnerability has been resolved: ALSA: firewire: isight: bound the     sample count to the packet payload isight_packet() takes the frame count from the device iso packet and     checks it only against the device claimed iso length. count = be32_to_cpu(payload->sample_count); if     (likely(count <= (length - 16) / 4)) isight_samples(isight, payload->samples, count); length is the iso     header data_length. It can be up to 0xffff. So the gate allows a count up to about 16379. isight_samples()     then copies count frames out of payload->samples into the PCM DMA buffer. payload->samples holds only 2 *     MAX_FRAMES_PER_PACKET values. The device multiplexes two samples per frame. A count past     MAX_FRAMES_PER_PACKET reads past the payload. A count past the buffer size writes past runtime->dma_area.
    The smallest PCM buffer is larger than MAX_FRAMES_PER_PACKET. Bounding the count to MAX_FRAMES_PER_PACKET     keeps both the read and the write in range. A malicious or faulty Apple iSight on the FireWire bus reaches     this during a normal capture. Add the MAX_FRAMES_PER_PACKET bound to the gate. (CVE-2026-64483)

The CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS-STREAM8:CLSA-2026:1792239979 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: kyber: fix out of bounds access when     preempted __blk_mq_sched_bio_merge() gets the ctx and hctx for the current CPU and passes the hctx to
    ->bio_merge(). kyber_bio_merge() then gets the ctx for the current CPU again and uses that to get the     corresponding Kyber context in the passed hctx. However, the thread may be preempted between the two calls     to blk_mq_get_ctx(), and the ctx returned the second time may no longer correspond to the passed hctx.
    This works accidentally most of the time, but it can cause us to read garbage if the second ctx came     from an hctx with more ctx's than the first one (i.e., if ctx->index_hw[hctx->type] > hctx->nr_ctx). This     manifested as this UBSAN array index out of bounds error reported by Jakub: UBSAN: array-index-out-of-     bounds in ../kernel/locking/qspinlock.c:130:9 index 13106 is out of range for type 'long unsigned int     [128]' Call Trace: dump_stack+0xa4/0xe5 ubsan_epilogue+0x5/0x40

BFQ and mq-deadline just use that, and Kyber can map the queues itself to avoid the mismatch.
    (CVE-2021-46984)

  - A use-after-free flaw was found in the Linux kernel's SGI GRU driver in the way the first     gru_file_unlocked_ioctl function is called by the user, where a fail pass occurs in the     gru_check_chiplet_assignment function. This flaw allows a local user to crash or potentially escalate     their privileges on the system. (CVE-2022-3424)

  - In the Linux kernel, the following vulnerability has been resolved: bpf, test_run: Fix alignment problem     in bpf_prog_test_run_skb() We got a syzkaller problem because of aarch64 alignment fault if KFENCE     enabled. When the size from user bpf program is an odd number, like 399, 407, etc, it will cause the     struct skb_shared_info's unaligned access. As seen below: BUG: KFENCE: use-after-free read in

  - In the Linux kernel, the following vulnerability has been resolved: usbnet: Fix linkwatch use-after-free     on disconnect usbnet uses the work usbnet_deferred_kevent() to perform tasks which may sleep. On     disconnect, completion of the work was originally awaited in ->ndo_stop(). But in 2003, that was moved to
    ->disconnect() by historic commit [PATCH] USB: usbnet, prevent exotic rtnl deadlock:
    https://git.kernel.org/tglx/history/c/0f138bbfd83c The change was made because back then, the kernel's     workqueue implementation did not allow waiting for a single work. One had to wait for completion of *all*     work by calling flush_scheduled_work(), and that could deadlock when waiting for usbnet_deferred_kevent()     with rtnl_mutex held in ->ndo_stop(). The commit solved one problem but created another: It causes a use-     after-free in USB Ethernet drivers aqc111.c, asix_devices.c, ax88179_178a.c, ch9200.c and smsc75xx.c: * If     the drivers receive a link change interrupt immediately before disconnect, they raise EVENT_LINK_RESET in     their (non-sleepable) ->status() callback and schedule usbnet_deferred_kevent(). *     usbnet_deferred_kevent() invokes the driver's ->link_reset() callback, which calls     netif_carrier_{on,off}(). * That in turn schedules the work linkwatch_event(). Because     usbnet_deferred_kevent() is awaited after unregister_netdev(), netif_carrier_{on,off}() may operate on an     unregistered netdev and linkwatch_event() may run after free_netdev(), causing a use-after-free. In 2010,     usbnet was changed to only wait for a single instance of usbnet_deferred_kevent() instead of *all* work by     commit 23f333a2bfaf (drivers/net: don't use flush_scheduled_work()). Unfortunately the commit neglected     to move the wait back to ->ndo_stop(). Rectify that omission at long last. (CVE-2022-50220)

To simply fix it, we could just pass @sign kmalloc'd from     crypt_message() and then we're done. Luckily, we don't seem to pass any other vmalloc'd buffers in     smb_rqst::rq_iov... Instead, let's map the correct pages and offsets from vmalloc buffers as well in     cifs_sg_set_buf() and then avoiding such oopses. (CVE-2022-50341)

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For the stable distribution (trixie), these problems have been fixed in     version 6.12.113-1.

    We recommend that you upgrade your linux packages.

    For the detailed security status of linux please refer to its security     tracker page at:
    https://security-tracker.debian.org/tracker/linux

    Further information about Debian Security Advisories, how to apply     these updates to your system and frequently asked questions can be     found at: https://www.debian.org/security/

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - dmaengine: wait for RCU readers before releasing dma_device dma_issue_pending_all() walks the     dma_device_list with list_for_each_entry_rcu() under rcu_read_lock(). dma_device_release() unlinks the     device with list_del_rcu() and then calls device->device_release() (which in many drivers, such as     plx_dma.c, directly calls kfree()). Because there is no grace period between unlinking the device and     freeing it, concurrent RCU readers in dma_issue_pending_all() can access the device after it has been     freed. The lockless walk originally relied on clients holding a dmaengine reference to pin the provider     module, and therefore the device, for as long as they might traverse the list. Commit 8ad342a86359     (dmaengine: Add reference counting to dma_device struct) decoupled the dma_device lifetime from the     module reference, so the device can now be released while a reader is still walking the list. Add     synchronize_rcu() before the device is freed, so RCU readers are guaranteed to have finished. Keep it     unconditional: providers that do not implement device_release() free the device themselves once     dma_async_device_unregister() returns. This call will delay for a grace period with dma_list_mutex held,     which is safe and only teardown path is delayed. (CVE-2026-98342)

Note that Nessus relies on the presence of the package as reported by the vendor.
