high Tenable Cloud Security Plugin ID 467373

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: audit: fix potential use-after-free in
audit_del_rule() `audit_del_rule()` destroys `e->rule.exe` via `audit_remove_mark_rule()` before unlinking
the rule from RCU-visible filter lists and waiting for a grace period. Concurrent readers in
`audit_filter()` and `audit_filter_rules()` still dereference `e->rule.exe`, while the fsnotify mark can
be freed on an independent lifetime path. This creates a use-after-free window during rule deletion. Fix
this by unlinking the rule from the RCU-visible lists and invoking `synchronize_rcu()` before calling
`audit_remove_mark_rule()` (and other rule removal helpers). This ensures that all existing RCU readers
have exited the critical section before any underlying resources are destroyed. (CVE-2026-74512)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18867.584.3 or later.
