Overview

CVE-2024-49956 is a high-severity vulnerability. It was published on October 21, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

gfs2: fix double destroy_workqueue error

When gfs2_fill_super() fails, destroy_workqueue() is called within

gfs2_gl_hash_clear(), and the subsequent code path calls

destroy_workqueue() on the same work queue again.

This issue can be fixed by setting the work queue pointer to NULL after

the first destroy_workqueue() call and checking for a NULL pointer

before attempting to destroy the work queue again.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
