In the Linux kernel, the following vulnerability has been resolved: netfilter: require Ethernet MAC header before using eth_hdr() `ip6t_eui64`, `xt_mac`, the `bitmap:ip,mac`, `hash:ip,mac`, and `hash:mac` ipset types, and `nf_log_syslog` access `eth_hdr(skb)` after either assuming that the skb is associated with an Ethernet device or checking only that the `ETH_HLEN` bytes at `skb_mac_header(skb)` lie between `skb->head` and `skb->data`. Make these paths first verify that the skb is associated with an Ethernet device, that the MAC header was set, and that it spans at least a full Ethernet header before accessing `eth_hdr(skb)`.

    In the Linux kernel, the following vulnerability has been resolved:

    net: bonding: fix NULL pointer dereference in bond_do_ioctl()

    In bond_do_ioctl(), slave_dev is obtained via __dev_get_by_name() whichcan return NULL if the requested     interface name does not exist. However,the subsequent slave_dbg() call is placed before the NULL check:

    slave_dev = __dev_get_by_name(net, ifr->ifr_slave);slave_dbg(bond_dev, slave_dev, slave_dev=%p:\n,     slave_dev); //hereif (!slave_dev)return -ENODEV;

    The slave_dbg() macro expands to netdev_dbg(bond_dev, (slave %s):  fmt,(slave_dev)->name, ...) which     unconditionally dereferences slave_dev->namebefore the NULL check is performed. This results in a NULL     pointerdereference kernel oops when a user calls bonding ioctl (e.g.SIOCBONDENSLAVE, SIOCBONDRELEASE,     etc.) with a non-existent slaveinterface name.

    This is reachable from userspace via the bonding ioctl interface withCAP_NET_ADMIN capability, making it a     potential local denial-of-servicevector.

    Fix by moving the slave_dbg() call after the NULL check. (CVE-2026-53337)

    In the Linux kernel, the following vulnerability has been resolved:

    signal: clear JOBCTL_PENDING_MASK for caller in zap_other_threads()

    When a multi-threaded process receives a stop signal (e.g., SIGSTOP),do_signal_stop() sets     JOBCTL_STOP_PENDING and JOBCTL_STOP_CONSUME on allthreads and sets signal->group_stop_count to the number     of threads. Ifone of the threads concurrently calls execve(), de_thread() invokeszap_other_threads() to     kill all other threads. zap_other_threads()aborts the pending group stop by resetting     signal->group_stop_count to 0and clears the JOBCTL_PENDING_MASK for all other threads. However, itfails to     clear the job control flags for the calling thread.

    When execve() completes, the calling thread returns to user mode andchecks for pending signals. Seeing the     stale JOBCTL_STOP_PENDING flag,it calls do_signal_stop(), which invokes     task_participate_group_stop().Since JOBCTL_STOP_CONSUME is still set, it attempts to decrement thealready-     zero signal->group_stop_count, triggering a warning:

    sig->group_stop_count == 0WARNING: CPU: 1 PID: 6475 at     kernel/signal.c:373task_participate_group_stop+0x215/0x2d0Call Trace:<TASK>do_signal_stop+0x3be/0x5c0     kernel/signal.c:2619get_signal+0xa8c/0x1330 kernel/signal.c:2884arch_do_signal_or_restart+0xbc/0x840     arch/x86/kernel/signal.c:337exit_to_user_mode_loop+0x8c/0x4d0     kernel/entry/common.c:98do_syscall_64+0x33e/0xf80     arch/x86/entry/syscall_64.c:100entry_SYSCALL_64_after_hwframe+0x77/0x7f</TASK>

    Fix this race condition by clearing the JOBCTL_PENDING_MASK for thecalling thread in zap_other_threads(),     ensuring it does not retain anystale job control state after the thread group is destroyed. This     alignswith other functions that tear down a thread group and abort groupstops, such as zap_process() and     complete_signal(), which correctlyclear these flags for all threads including the current one.
    (CVE-2026-53352)

    In the Linux kernel, the following vulnerability has been resolved:

    arm64: errata: Mitigate TLBI errata on various Arm CPUs

    A number of CPUs developed by Arm suffer from errata whereby a broadcastTLBI;DSB sequence may complete     before the global observation of writeswhich are translated by an affected TLB entry.

    These errata ONLY affect the completion of memory accesses which havebeen translated by an invalidated TLB     entry, and these errata DO NOTaffect the actual invalidation of TLB entries. TLB entries are     removedcorrectly.

    This issue has been assigned CVE ID CVE-2025-10263.

    To mitigate this issue, Arm recommends that software follows anyaffected TLBI;DSB sequence with an     additional TLBI;DSB, which willensure that all memory write effects affected by the first TLBI havebeen     globally observed. The additional TLBI can use any operation thatis broadcast to affected CPUs, and the     additional DSB can use any optionthat is sufficient to complete the additional TLBI.

    The ARM64_WORKAROUND_REPEAT_TLBI workaround is sufficient to mitigatethe issue. Enable this workaround for     affected CPUs, and update thesilicon errata documentation accordingly.

    Note that due to the manner in which Arm develops IP and tracks errata,some CPUs share a common erratum     number. (CVE-2026-53354)

    ipv6: Fix a potential NPD in cleanup_prefix_route()

    Note that the other callers of addrconf_get_prefix_route() are notsusceptible to this bug:

    1. addrconf_prefix_rcv(): Requests a route with the 'RTF_ADDRCONF |RTF_PREFIX_RT' flags which are not set     on fib6_null_entry.

    2. modify_prefix_route(): Fixed by commit a747e02430df (ipv6: avoidpossible NULL deref in     modify_prefix_route()).

    3. __ipv6_ifa_notify(): Calls ip6_del_rt() which specifically checks forfib6_null_entry and returns an     error.

    In the Linux kernel, the following vulnerability has been resolved:

    net: bonding: fix NULL pointer dereference in bond_do_ioctl()

    In bond_do_ioctl(), slave_dev is obtained via __dev_get_by_name() whichcan return NULL if the requested     interface name does not exist. However,the subsequent slave_dbg() call is placed before the NULL check:

    slave_dev = __dev_get_by_name(net, ifr->ifr_slave);slave_dbg(bond_dev, slave_dev, slave_dev=%p:\n,     slave_dev); //hereif (!slave_dev)return -ENODEV;

    The slave_dbg() macro expands to netdev_dbg(bond_dev, (slave %s):  fmt,(slave_dev)->name, ...) which     unconditionally dereferences slave_dev->namebefore the NULL check is performed. This results in a NULL     pointerdereference kernel oops when a user calls bonding ioctl (e.g.SIOCBONDENSLAVE, SIOCBONDRELEASE,     etc.) with a non-existent slaveinterface name.

    This is reachable from userspace via the bonding ioctl interface withCAP_NET_ADMIN capability, making it a     potential local denial-of-servicevector.

    Fix by moving the slave_dbg() call after the NULL check. (CVE-2026-53337)

    In the Linux kernel, the following vulnerability has been resolved:

    netfilter: nf_conntrack: destroy stale expectfn expectations on unregister

    NAT helpers such as nf_nat_h323 store a raw pointer to module text inexp->expectfn (e.g.
    ip_nat_q931_expect). nf_ct_helper_expectfn_unregister()only unlinks the callback descriptor and never     walks the expectation table,so an expectation pending at module removal survives with a     danglingexp->expectfn into freed module text.

    When the expected connection arrives, init_conntrack() invokesexp->expectfn(), now a stale pointer into     the unloaded module. Reproducedon a KASAN build by loading the H.323 helpers, creating a Q.931expectation,     unloading nf_nat_h323, then connecting to the expected port:

    Reaching the dangling state requires CAP_SYS_MODULE in the initial usernamespace to remove a NAT helper     that still has live expectations, so thisis a robustness fix; leaving an expectation pointing at freed     text is wrongregardless.

    Add nf_ct_helper_expectfn_destroy(), which walks the expectation table anddrops every expectation whose
    ->expectfn matches the descriptor being torndown. Call it from each NAT helper's exit path after the     existing RCU graceperiod, so no expectation outlives the code it points at and no extrasynchronize_rcu()     is introduced. With the fix, the same reproducer runs tocompletion without the Oops. (CVE-2026-53349)

    In the Linux kernel, the following vulnerability has been resolved:

    signal: clear JOBCTL_PENDING_MASK for caller in zap_other_threads()

    When a multi-threaded process receives a stop signal (e.g., SIGSTOP),do_signal_stop() sets     JOBCTL_STOP_PENDING and JOBCTL_STOP_CONSUME on allthreads and sets signal->group_stop_count to the number     of threads. Ifone of the threads concurrently calls execve(), de_thread() invokeszap_other_threads() to     kill all other threads. zap_other_threads()aborts the pending group stop by resetting     signal->group_stop_count to 0and clears the JOBCTL_PENDING_MASK for all other threads. However, itfails to     clear the job control flags for the calling thread.

    When execve() completes, the calling thread returns to user mode andchecks for pending signals. Seeing the     stale JOBCTL_STOP_PENDING flag,it calls do_signal_stop(), which invokes     task_participate_group_stop().Since JOBCTL_STOP_CONSUME is still set, it attempts to decrement thealready-     zero signal->group_stop_count, triggering a warning:

    sig->group_stop_count == 0WARNING: CPU: 1 PID: 6475 at     kernel/signal.c:373task_participate_group_stop+0x215/0x2d0Call Trace:<TASK>do_signal_stop+0x3be/0x5c0     kernel/signal.c:2619get_signal+0xa8c/0x1330 kernel/signal.c:2884arch_do_signal_or_restart+0xbc/0x840     arch/x86/kernel/signal.c:337exit_to_user_mode_loop+0x8c/0x4d0     kernel/entry/common.c:98do_syscall_64+0x33e/0xf80     arch/x86/entry/syscall_64.c:100entry_SYSCALL_64_after_hwframe+0x77/0x7f</TASK>

    Fix this race condition by clearing the JOBCTL_PENDING_MASK for thecalling thread in zap_other_threads(),     ensuring it does not retain anystale job control state after the thread group is destroyed. This     alignswith other functions that tear down a thread group and abort groupstops, such as zap_process() and     complete_signal(), which correctlyclear these flags for all threads including the current one.

    In the Linux kernel, the following vulnerability has been resolved:

    arm64: errata: Mitigate TLBI errata on various Arm CPUs

    A number of CPUs developed by Arm suffer from errata whereby a broadcastTLBI;DSB sequence may complete     before the global observation of writeswhich are translated by an affected TLB entry.

    These errata ONLY affect the completion of memory accesses which havebeen translated by an invalidated TLB     entry, and these errata DO NOTaffect the actual invalidation of TLB entries. TLB entries are     removedcorrectly.

    This issue has been assigned CVE ID CVE-2025-10263.

    To mitigate this issue, Arm recommends that software follows anyaffected TLBI;DSB sequence with an     additional TLBI;DSB, which willensure that all memory write effects affected by the first TLBI havebeen     globally observed. The additional TLBI can use any operation thatis broadcast to affected CPUs, and the     additional DSB can use any optionthat is sufficient to complete the additional TLBI.

    The ARM64_WORKAROUND_REPEAT_TLBI workaround is sufficient to mitigatethe issue. Enable this workaround for     affected CPUs, and update thesilicon errata documentation accordingly.

    Note that due to the manner in which Arm develops IP and tracks errata,some CPUs share a common erratum     number. (CVE-2026-53354)

    To mitigate this issue, Arm recommends that software follows anyaffected TLBI;DSB sequence with an     additional TLBI;DSB, which willensure that all memory write effects affected by the first TLBI havebeen     globally observed. The additional TLBI can use any operation thatis broadcast to affected CPUs, and the     additional DSB can use any optionthat is sufficient to complete the additional TLBI.

    The ARM64_WORKAROUND_REPEAT_TLBI workaround is sufficient to mitigatethe issue. Enable this workaround for     affected CPUs, and update thesilicon errata documentation accordingly.

    Note that due to the manner in which Arm develops IP and tracks errata,some CPUs share a common erratum     number. (CVE-2026-53354)

Debian Bug     : 1130365 1119093

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

    For Debian 12 bookworm, these problems have been fixed in version     6.1.176-1.  This version additionally includes many more bug fixes     from stable updates 6.1.175 and 6.1.176.

    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 LTS security advisories, how to apply     these updates to your system and frequently asked questions can be     found at: https://wiki.debian.org/LTS     Attachment:

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.

  - netfilter: require Ethernet MAC header before using eth_hdr() `ip6t_eui64`, `xt_mac`, the `bitmap:ip,mac`,     `hash:ip,mac`, and `hash:mac` ipset types, and `nf_log_syslog` access `eth_hdr(skb)` after either assuming     that the skb is associated with an Ethernet device or checking only that the `ETH_HLEN` bytes at     `skb_mac_header(skb)` lie between `skb->head` and `skb->data`. Make these paths first verify that the skb     is associated with an Ethernet device, that the MAC header was set, and that it spans at least a full     Ethernet header before accessing `eth_hdr(skb)`. (CVE-2026-53131)

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

An update of the linux package has been released.
