In the Linux kernel, the following vulnerability has been resolved: net: ioam6: fix OOB and missing lock When trace->type.bit6 is set: if (trace->type.bit6) { ... queue = skb_get_tx_queue(dev, skb); qdisc = rcu_dereference(queue->qdisc); This code can lead to an out-of-bounds access of the dev->_tx[] array when is_input is true. In such a case, the packet is on the RX path and skb->queue_mapping contains the RX queue index of the ingress device. If the ingress device has more RX queues than the egress device (dev) has TX queues, skb_get_queue_mapping(skb) will exceed dev->num_tx_queues. Add a check to avoid this situation since skb_get_tx_queue() does not clamp the index. This issue has also revealed that per queue visibility cannot be accurate and will be replaced later as a new feature. While at it, add missing lock around qdisc_qstats_qlen_backlog(). The function __ioam6_fill_trace_data() is called from both softirq and process contexts, hence the use of spin_lock_bh() here.

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

    audit: fix incorrect inheritable capability in CAPSET records

    __audit_log_capset() records the effective capability set into theinheritable field due to a copy-paste     error. Every CAPSET auditrecord therefore reports cap_pi (process inheritable) with the valueof     cap_effective instead of cap_inheritable.

    This silently corrupts audit data used for compliance and forensicanalysis: an attacker who modifies     inheritable capabilities toprepare for a privilege-escalating exec would have the change maskedin the     audit trail.

    mailbox: add sanity check for channel array

    Fail gracefully if there is no channel array attached to the mailboxcontroller. Otherwise the later     dereference will cause an OOPS whichmight not be seen because mailbox controllers might instantiate     veryearly. Remove the comment explaining the obvious while here. (CVE-2026-53295)

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

    scsi: sg: Resolve soft lockup issue when opening /dev/sgX (CVE-2026-53304)

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

Tenable has extracted the preceding description block directly from the tested product 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: ioam6: fix OOB and missing lock When trace->type.bit6 is set: if (trace->type.bit6) { ... queue =     skb_get_tx_queue(dev, skb); qdisc = rcu_dereference(queue->qdisc); This code can lead to an out-of-bounds     access of the dev->_tx[] array when is_input is true. In such a case, the packet is on the RX path and     skb->queue_mapping contains the RX queue index of the ingress device. If the ingress device has more RX     queues than the egress device (dev) has TX queues, skb_get_queue_mapping(skb) will exceed     dev->num_tx_queues. Add a check to avoid this situation since skb_get_tx_queue() does not clamp the index.
    This issue has also revealed that per queue visibility cannot be accurate and will be replaced later as a     new feature. While at it, add missing lock around qdisc_qstats_qlen_backlog(). The function
    __ioam6_fill_trace_data() is called from both softirq and process contexts, hence the use of     spin_lock_bh() here. (CVE-2026-43083)

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