critical Tenable Self-Hosted Container Security Plugin ID 475474

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: nvme: add missing SRCU grace period in
 error path nvme_alloc_ns() error path at out_unlink_ns removes ns from the namespace head siblings list
 with list_del_rcu(&ns->siblings) but does not wait for SRCU readers before freeing the namespace struct.
 Multipath code iterates the head->list under srcu_read_lock() in nvme_find_path() and
 nvme_mpath_revalidate_paths(), so a concurrent reader can still hold a reference to ns when kfree(ns)
 runs. The normal removal path in nvme_ns_remove() correctly calls synchronize_srcu(&ns->head->srcu) after
 list_del_rcu() to wait for in-progress readers. Add the same grace period in the error path.
 (CVE-2026-89972)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19999.44.106 or later.
