Overview

CVE-2024-56749 is a high-severity vulnerability. It was published on December 29, 2024 and has a CVSS 3.1 base score of 7.5 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

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

dlm: fix dlm_recover_members refcount on error

If dlm_recover_members() fails we don't drop the references of the

previous created root_list that holds and keep all rsbs alive during the

recovery. It might be not an unlikely event because ping_members() could

run into an -EINTR if another recovery progress was triggered 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.
