    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:

    Oops: int3: 0000 [#1] SMP KASAN NOPTIRIP: 0010:0xffffffffa06102d1init_conntrack.isra.0
    (net/netfilter/nf_conntrack_core.c:1862)nf_conntrack_in
    (net/netfilter/nf_conntrack_core.c:2049)ipv4_conntrack_local
    (net/netfilter/nf_conntrack_proto.c:223)nf_hook_slow (net/netfilter/core.c:619)__ip_local_out

    (net/socket.c:2167)Modules linked in: nf_conntrack_h323 [last unloaded: nf_nat_h323]

    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

    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)
