CVSS v3.1
5.5
Medium
| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.6.50
Description
The issue is related to a null pointer use in the destroy workqueue function within the init cifs error path in the Linux kernel's cifs component. This could potentially allow an attacker to cause a denial of service. The problem was identified by a Smack static checker warning in the fs/smb/client/cifsfs.c file, specifically at line 1981 in the init cifs function, where it was assumed that 'serverclose wq' could be null.
Recommendations
To resolve the issue, update the Linux kernel to version 6.6.50 or later.
As a temporary workaround, consider disabling the cifs component until a patch is available.
