Overview

CVE-2024-56564 is a medium-severity vulnerability. It was published on December 27, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

ceph: pass cred pointer to ceph_mds_auth_match()

This eliminates a redundant get_current_cred() call, because

ceph_mds_check_access() has already obtained this pointer.

As a side effect, this also fixes a reference leak in

ceph_mds_auth_match(): by omitting the get_current_cred() call, no

additional cred reference is taken.

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.
