Overview

CVE-2026-23024 is a medium-severity vulnerability. It was published on January 31, 2026 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:

idpf: fix memory leak of flow steer list on rmmod

The flow steering list maintains entries that are added and removed as

ethtool creates and deletes flow steering rules. Module removal with active

entries causes memory leak as the list is not properly cleaned up.

Prevent this by iterating through the remaining entries in the list and

freeing the associated memory during module removal. Add a spinlock

(flow_steer_list_lock) to protect the list access from multiple threads.

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.
