In the Linux kernel, the following vulnerability has been resolved: net: atm: fix crash due to unvalidated vcc pointer in sigd_send() Reproducer available at [1]. The ATM send path (sendmsg -> vcc_sendmsg -> sigd_send) reads the vcc pointer from msg->vcc and uses it directly without any validation. This pointer comes from userspace via sendmsg() and can be arbitrarily forged: int fd = socket(AF_ATMSVC, SOCK_DGRAM, 0); ioctl(fd, ATMSIGD_CTRL); // become ATM signaling daemon struct msghdr msg = { .msg_iov = &iov, ... }; *(unsigned long *)(buf + 4) = 0xdeadbeef; // fake vcc pointer sendmsg(fd, &msg, 0); // kernel dereferences 0xdeadbeef In normal operation, the kernel sends the vcc pointer to the signaling daemon via sigd_enq() when processing operations like connect(), bind(), or listen(). The daemon is expected to return the same pointer when responding. However, a malicious daemon can send arbitrary pointer values. Fix this by introducing find_get_vcc() which validates the pointer by searching through vcc_hash (similar to how sigd_close() iterates over all VCCs), and acquires a reference via sock_hold() if found. Since struct atm_vcc embeds struct sock as its first member, they share the same lifetime. Therefore using sock_hold/sock_put is sufficient to keep the vcc alive while it is being used. Note that there may be a race with sigd_close() which could mark the vcc with various flags (e.g., ATM_VF_RELEASED) after find_get_vcc() returns. However, sock_hold() guarantees the memory remains valid, so this race only affects the logical state, not memory safety. [1]: https://gist.github.com/mrpre/1ba5949c45529c511152e2f4c755b0f3

  - In the Linux kernel, the following vulnerability has been resolved: ipv6: use RCU in ip6_xmit() Use RCU in     ip6_xmit() in order to use dst_dev_rcu() to prevent possible UAF. (CVE-2025-40135)

  - This vulnerability was found and addressed by AMD. We are documenting it in the Security Update Guide to     encourage customers to install the May 2026 version of Windows as soon as possible. The vulnerability     assigned to this CVE is in certain processor models offered by AMD. The mitigation for this vulnerability     requires a Windows update. This CVE is being documented in the Security Update Guide to announce that the     latest builds of Windows enable the mitigation and provide protection against the vulnerability. Please     see the following for more information: AMD-SB-7052 (CVE-2025-54518)

  - In the Linux kernel, the following vulnerability has been resolved: dst: fix races in     rt6_uncached_list_del() and rt_del_uncached_list() syzbot was able to crash the kernel in     rt6_uncached_list_flush_dev() in an interesting way [1] Crash happens in list_del_init()/INIT_LIST_HEAD()     while writing list->prev, while the prior write on list->next went well. static inline void     INIT_LIST_HEAD(struct list_head *list) { WRITE_ONCE(list->next, list); // This went well     WRITE_ONCE(list->prev, list); // Crash, @list has been freed. } Issue here is that rt6_uncached_list_del()     did not attempt to lock ul->lock, as list_empty(&rt->dst.rt_uncached) returned true because the     WRITE_ONCE(list->next, list) happened on the other CPU. We might use list_del_init_careful() and     list_empty_careful(), or make sure rt6_uncached_list_del() always grabs the spinlock whenever     rt->dst.rt_uncached_list has been set. A similar fix is neeed for IPv4.

  - In the Linux kernel, the following vulnerability has been resolved: tls: Fix race condition in     tls_sw_cancel_work_tx() This issue was discovered during a code audit. After cancel_delayed_work_sync() is     called from tls_sk_proto_close(), tx_work_handler() can still be scheduled from paths such as the Delayed     ACK handler or ksoftirqd. As a result, the tx_work_handler() worker may dereference a freed TLS object.
    The following is a simple race scenario: cpu0 cpu1 tls_sk_proto_close() tls_sw_cancel_work_tx()     tls_write_space() tls_sw_write_space() if (!test_and_set_bit(BIT_TX_SCHEDULED, &tx_ctx->tx_bitmask))     set_bit(BIT_TX_SCHEDULED, &ctx->tx_bitmask); cancel_delayed_work_sync(&ctx->tx_work.work);
    schedule_delayed_work(&tx_ctx->tx_work.work, 0); To prevent this race condition,     cancel_delayed_work_sync() is replaced with disable_delayed_work_sync(). (CVE-2026-23240)

  - In the Linux kernel, the following vulnerability has been resolved: RDMA/umad: Reject negative data_len in     ib_umad_write ib_umad_write computes data_len from user-controlled count and the MAD header sizes. With a     mismatched user MAD header size and RMPP header length, data_len can become negative and reach     ib_create_send_mad(). This can make the padding calculation exceed the segment size and trigger an out-of-     bounds memset in alloc_send_rmpp_list(). Add an explicit check to reject negative data_len before creating     the send buffer. KASAN splat: [ 211.363464] BUG: KASAN: slab-out-of-bounds in     ib_create_send_mad+0xa01/0x11b0 [ 211.364077] Write of size 220 at addr ffff88800c3fa1f8 by task     spray_thread/102 [ 211.365867] ib_create_send_mad+0xa01/0x11b0 [ 211.365887] ib_umad_write+0x853/0x1c80     (CVE-2026-23243)

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

    For Debian 11 bullseye, these problems have been fixed in version     6.1.170-1~deb11u1.

    We recommend that you upgrade your linux-6.1 packages.

    For the detailed security status of linux-6.1 please refer to     its security tracker page at:
    https://security-tracker.debian.org/tracker/linux-6.1

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

    For the oldstable distribution (bookworm), these problems have been fixed     in version 6.1.170-1.

    We recommend that you upgrade your linux packages.

    For the detailed security status of linux please refer to its security     tracker page at:

    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 6.12.85-1.

    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.

  - net: atm: fix crash due to unvalidated vcc pointer in sigd_send() Reproducer available at [1]. The ATM     send path (sendmsg -> vcc_sendmsg -> sigd_send) reads the vcc pointer from msg->vcc and uses it directly     without any validation. This pointer comes from userspace via sendmsg() and can be arbitrarily forged: int     fd = socket(AF_ATMSVC, SOCK_DGRAM, 0); ioctl(fd, ATMSIGD_CTRL); // become ATM signaling daemon struct     msghdr msg = { .msg_iov = &iov, ... }; *(unsigned long *)(buf + 4) = 0xdeadbeef; // fake vcc pointer     sendmsg(fd, &msg, 0); // kernel dereferences 0xdeadbeef In normal operation, the kernel sends the vcc     pointer to the signaling daemon via sigd_enq() when processing operations like connect(), bind(), or     listen(). The daemon is expected to return the same pointer when responding. However, a malicious daemon     can send arbitrary pointer values. Fix this by introducing find_get_vcc() which validates the pointer by     searching through vcc_hash (similar to how sigd_close() iterates over all VCCs), and acquires a reference     via sock_hold() if found. Since struct atm_vcc embeds struct sock as its first member, they share the same     lifetime. Therefore using sock_hold/sock_put is sufficient to keep the vcc alive while it is being used.
    Note that there may be a race with sigd_close() which could mark the vcc with various flags (e.g.,     ATM_VF_RELEASED) after find_get_vcc() returns. However, sock_hold() guarantees the memory remains valid,     so this race only affects the logical state, not memory safety. [1]:

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