Google: sys-kernel/cchost-kernel-6_12, sys-kernel/csql-kernel-6_12, sys-kernel/lakitu-kernel-6_12, sys-kernel/lakitu-nc-kernel-6_12: security update to 19506.448.8

high Tenable Self-Hosted Container Security Plugin ID 469006

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: apparmor: check label build before
no_new_privs test aa_change_profile() builds a replacement label with fn_label_build_in_scope() before the
no_new_privs subset check. The build helper can fail and return NULL or an ERR_PTR, but the result was
passed to aa_label_is_unconfined_subset() before the existing IS_ERR_OR_NULL() check. Reuse the existing
target-label build failure handling immediately after the build. This preserves the current audit handling
while preventing the subset helper from dereferencing an invalid label. (CVE-2026-72460)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.448.8 or later.
