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.

  - bridge: mrp: reject zero test interval to avoid OOM panic br_mrp_start_test() and br_mrp_start_in_test()     accept the user-supplied interval value from netlink without validation. When interval is 0,     usecs_to_jiffies(0) yields 0, causing the delayed work (br_mrp_test_work_expired /     br_mrp_in_test_work_expired) to reschedule itself with zero delay. This creates a tight loop on     system_percpu_wq that allocates and transmits MRP test frames at maximum rate, exhausting all system     memory and causing a kernel panic via OOM deadlock. The same zero-interval issue applies to     br_mrp_start_in_test_parse() for interconnect test frames. Use NLA_POLICY_MIN(NLA_U32, 1) in the     nla_policy tables for both IFLA_BRIDGE_MRP_START_TEST_INTERVAL and IFLA_BRIDGE_MRP_START_IN_TEST_INTERVAL,     so zero is rejected at the netlink attribute parsing layer before the value ever reaches the workqueue     scheduling code. This is consistent with how other bridge subsystems (br_fdb, br_mst) enforce range     constraints on netlink attributes. (CVE-2026-31420)

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

The remote Debian 13 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-6355 advisory.

    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 6.12.94-1.

    We recommend that you upgrade your linux packages.
