In the Linux kernel, the following vulnerability has been resolved: octeontx2-af: fix NULL deref in NIX TM tree debugfs read path rvu_dbg_nix_tm_tree_display() dereferences pfvf->sq_ctx without checking whether the SQ context has been allocated. Reading /sys/kernel/debug/octeontx2/nix/tm_tree for a NIX LF whose transmit queues are not set up triggers a kernel oops. Guard the read path the same way rvu_dbg_nix_tm_tree_write() already does and return -EINVAL with a seq_file message when sq_ctx is NULL.

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 ... Call Trace: <TASK> [...] do_trace_event_raw_event_event_da_monitor+0xd6/0x1a0     ? __pfx_do_trace_event_raw_event_event_da_monitor+0x10/0x10 ? trace_event_sncid+0x83/0x200     trace_event_sncid+0x163/0x200 [...] The buggy address belongs to the variable: automaton_snep+0x4e0/0x5e0     This is caused by the tracepoints reading 32 bytes __array instead of __string from the automata     definition. 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.

An update of the linux package has been released.

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

  - In the Linux kernel, the following vulnerability has been resolved: octeontx2-af: fix NULL deref in NIX TM     tree debugfs read path rvu_dbg_nix_tm_tree_display() dereferences pfvf->sq_ctx without checking whether     the SQ context has been allocated.
