high Tenable Cloud Security Plugin ID 469127

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: lockd: Plug nlm_file leak when
nlm_do_fopen() fails A client can repeatedly drive nlm_do_fopen() failures by presenting file handles that
the underlying export rejects. After kzalloc_obj() succeeds in nlm_lookup_file(), the freshly allocated
nlm_file is not yet inserted into nlm_files[]. The nlm_do_fopen() failure path jumps to out_unlock, which
releases nlm_file_mutex and returns without freeing the allocation, so each failure leaks one nlm_file.
Route the failure through out_free so kfree() runs before the function returns. (CVE-2026-72219)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.655.6 or later.
