high Tenable Self-Hosted Container Security Plugin ID 468664

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: dax: read holder_ops once in
 dax_holder_notify_failure() dax_holder_notify_failure() reads dax_dev->holder_ops twice without
 READ_ONCE() -- once for the NULL check and once for the indirect notify_failure() call. A concurrent
 fs_put_dax() can clear holder_ops between the two reads, so the check can observe a non-NULL pointer while
 the call dereferences NULL. (kill_dax() also clears holder_ops, but only after synchronize_srcu(), so it
 cannot race a reader that is inside dax_read_lock(); fs_put_dax() does no such synchronization.) Fetch
 holder_ops once into a local with READ_ONCE() so the NULL check and the indirect call observe the same
 value. (CVE-2026-93073)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.700.7 or later.
