The remote RockyLinux host is missing one or more security updates.

Description

The remote RockyLinux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2026:38491 advisory.

 * kernel: Linux kernel: Memory leak in networking due to incorrect GRO packet handling (CVE-2026-22979)

 * kernel: rtmutex: Use waiter::task instead of current in remove_waiter() (CVE-2026-43499)

 * kernel: net: bridge: use a stable FDB dst snapshot in RCU readers (CVE-2026-46086)

 * kernel: crypto: ccp - copy IV using skcipher ivsize (CVE-2026-53016)

 * kernel: futex/requeue: Prevent NULL pointer dereference in remove_waiter() on self-deadlock (CVE-2026-53166)

 Bug Fix(es) and Enhancement(s):

 * Kernel panic very early during boot while reading a tracefs file (available_filter_functions) due to invalid module name pointer [9.8.z] (JIRA:Rocky Linux-183236)

Tenable has extracted the preceding description block directly from the RockyLinux security advisory.

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

Solution

Update the affected packages.
