low Tenable Cloud Security Plugin ID 471412

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: landlock: Fix LOG_SUBDOMAINS_OFF
 inheritance across fork() hook_cred_transfer() only copies the Landlock security blob when the source
 credential has a domain. This is inconsistent with landlock_restrict_self() which can set
 LOG_SUBDOMAINS_OFF on a credential without creating a domain (via the ruleset_fd=-1 path): the field is
 committed but not preserved across fork() because the child's prepare_creds() calls hook_cred_transfer()
 which skips the copy when domain is NULL. This breaks the documented use case where a process mutes
 subdomain logs before forking sandboxed children: the children lose the muting and their domains produce
 unexpected audit records. Fix this by unconditionally copying the Landlock credential blob.
 (CVE-2026-46057)

Solution

Update the sys-kernel/cchost-kernel-6_18 library and its related packages to version 19804.0.0 or later.
