In the Linux kernel, the following vulnerability has been resolved: net: team: free skb when broadcast has no txable port bc_transmit() sends the original skb through the last txable port. When no port is txable, it returns false without consuming the skb, but team_xmit() still returns NETDEV_TX_OK. AF_PACKET sends then retain the skb and its socket write-memory charge. A TX-enabled, link-down port keeps the broadcast transmit op installed. Carrier can stay up through a second link-up, TX-disabled port or be forced on by userspace. Free the original skb on the no-port path while leaving the existing drop accounting intact. Discovered by Sashiko during review of previous commit.

The AlmaLinux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1793866396 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: rv: Use strings in da monitors     tracepoints Using DA monitors tracepoints with KASAN enabled triggers the following warning: BUG: KASAN:
    global-out-of-bounds in do_trace_event_raw_event_event_da_monitor+0xd6/0x1a0 Read of size 32 at addr     ffffffffaada8980 by task ...

Such strings are literals and reading 32 bytes ends up in out of bound memory accesses (e.g.
    the next automaton's data in this case). The error is harmless as, while printing the string, we stop at     the null terminator, but it should still be fixed. Use the __string facilities while defining the     tracepoints to avoid reading out of bound memory. (CVE-2025-38636)

  - In the Linux kernel, the following vulnerability has been resolved: iommufd: Prevent ALIGN() overflow When     allocating IOVA the candidate range gets aligned to the target alignment. If the range is close to     ULONG_MAX then the ALIGN() can wrap resulting in a corrupted iova. Open code the ALIGN() using     get_add_overflow() to prevent this. This simplifies the checks as we don't need to check for length     earlier either. Consolidate the two copies of this code under a single helper. This bug would allow     userspace to create a mapping that overlaps with some other mapping or a reserved range. (CVE-2025-38688)

  - In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: fix NULL dereference in     ath11k_qmi_m3_load() If ab->fw.m3_data points to data, then fw pointer remains null. Further, if m3_mem is     not allocated, then fw is dereferenced to be passed to ath11k_err function. Replace fw->size by m3_len.
    Found by Linux Verification Center (linuxtesting.org) with SVACE. (CVE-2025-39991)

  - In the Linux kernel, the following vulnerability has been resolved: libceph: prevent potential out-of-     bounds writes in handle_auth_session_key() The len field originates from untrusted network packets.
    Boundary checks have been added to prevent potential out-of-bounds writes when decrypting the connection     secret or processing service tickets. [ idryomov: changelog ] (CVE-2025-68284)

  - In the Linux kernel, the following vulnerability has been resolved: tipc: fix bc_ackers underflow on     duplicate GRP_ACK_MSG The GRP_ACK_MSG handler in tipc_group_proto_rcv() currently decrements bc_ackers on     every inbound group ACK, even when the same member has already acknowledged the current broadcast round.
    Because bc_ackers is a u16, a duplicate ACK received after the last legitimate ACK wraps the counter to     65535. Once wrapped, tipc_group_bc_cong() keeps reporting congestion and later group broadcasts on the     affected socket stay blocked until the group is recreated. Fix this by ignoring duplicate or stale ACKs     before touching bc_acked or bc_ackers. This makes repeated GRP_ACK_MSG handling idempotent and prevents     the underflow path. (CVE-2026-31662)

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

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1793786843 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: soc: qcom: qmi_encdec: Restrict string     length in decode The QMI TLV value for strings in a lot of qmi element info structures account for null     terminated strings with MAX_LEN + 1. If a string is actually MAX_LEN + 1 length, this will cause an out of     bounds access when the NULL character is appended in decoding. (CVE-2023-53729)

  - In the Linux kernel, the following vulnerability has been resolved: rv: Use strings in da monitors     tracepoints Using DA monitors tracepoints with KASAN enabled triggers the following warning: BUG: KASAN:

  - In the Linux kernel, the following vulnerability has been resolved: perf: arm_spe: Prevent overflow in     PERF_IDX2OFF() Cast nr_pages to unsigned long to avoid overflow when handling large AUX buffer sizes (>= 2     GiB). (CVE-2025-40081)

  - In the Linux kernel, the following vulnerability has been resolved: arch_topology: Fix incorrect error     check in topology_parse_cpu_capacity() Fix incorrect use of PTR_ERR_OR_ZERO() in     topology_parse_cpu_capacity() which causes the code to proceed with NULL clock pointers. The current logic     uses !PTR_ERR_OR_ZERO(cpu_clk) which evaluates to true for both valid pointers and NULL, leading to     potential NULL pointer dereference in clk_get_rate(). Per include/linux/err.h documentation,     PTR_ERR_OR_ZERO(ptr) returns: The error code within @ptr if it is an error pointer; 0 otherwise. This     means PTR_ERR_OR_ZERO() returns 0 for both valid pointers AND NULL pointers. Therefore     !PTR_ERR_OR_ZERO(cpu_clk) evaluates to true (proceed) when cpu_clk is either valid or NULL, causing     clk_get_rate(NULL) to be called when of_clk_get() returns NULL. Replace with !IS_ERR_OR_NULL(cpu_clk)     which only proceeds for valid pointers, preventing potential NULL pointer dereference in clk_get_rate().

  - In the Linux kernel, the following vulnerability has been resolved: platform/x86/amd/pmc: Add support for     Van Gogh SoC The ROG Xbox Ally (non-X) SoC features a similar architecture to the Steam Deck. While the     Steam Deck supports S3 (s2idle causes a crash), this support was dropped by the Xbox Ally which only S0ix     suspend. Since the handler is missing here, this causes the device to not suspend and the AMD GPU driver     to crash while trying to resume afterwards due to a power hang. (CVE-2025-68334)

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: team: free skb when broadcast has no txable port bc_transmit() sends the original skb through the     last txable port. When no port is txable, it returns false without consuming the skb, but team_xmit()     still returns NETDEV_TX_OK. AF_PACKET sends then retain the skb and its socket write-memory charge. A TX-     enabled, link-down port keeps the broadcast transmit op installed. Carrier can stay up through a second     link-up, TX-disabled port or be forced on by userspace. Free the original skb on the no-port path while     leaving the existing drop accounting intact. Discovered by Sashiko during review of previous commit.
    (CVE-2026-99026)

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