high Tenable Self-Hosted Container Security Plugin ID 469386

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: NFSD: Handle layout stid in
nfsd4_drop_revoked_stid() nfsd4_drop_revoked_stid() has no SC_TYPE_LAYOUT case, so when a client sends
FREE_STATEID for an admin-revoked layout stid, the default branch releases cl_lock and returns without
unhashing or releasing the stid. The stid remains in the IDR and on the per-client list until the client
is destroyed. Remove the layout stid from the per-client list and call nfs4_put_stid() to drop the
creation reference. When the refcount reaches zero, nfsd4_free_layout_stateid() handles the remaining
cleanup: cancelling the fence worker, removing from the per-file list, and freeing the slab object.
(CVE-2026-74316)

Solution

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