high Tenable Cloud Security Plugin ID 459587

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: smb: client: fix potential UAF in
 smb2_close_cached_fid() find_or_create_cached_dir() could grab a new reference after kref_put() had seen
 the refcount drop to zero but before cfid_list_lock is acquired in smb2_close_cached_fid(), leading to
 use-after-free. Switch to kref_put_lock() so cfid_release() is called with cfid_list_lock held, closing
 that gap. (CVE-2025-40328)

Solution

Update the linux library and its related packages to version 6.12.63-1 or later.
