medium Tenable Self-Hosted Container Security Plugin ID 464085

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: cifs: prevent NULL pointer dereference
 in UTF16 conversion There can be a NULL pointer dereference bug here. NULL is passed to
 __cifs_sfu_make_node without checks, which passes it unchecked to cifs_strndup_to_utf16, which in turn
 passes it to cifs_local_to_utf16_bytes where '*from' is dereferenced, causing a crash. This patch adds a
 check for NULL 'src' in cifs_strndup_to_utf16 and returns NULL early to prevent dereferencing NULL
 pointer. Found by Linux Verification Center (linuxtesting.org) with SVACE (CVE-2025-39838)

Solution

Update the linux library and its related packages to version 6.1.153-1 or later.
