Name of the Vulnerable Software and Affected Versions
Linux Kernel versions prior to v5.4.162
Description
The issue is related to the iavf disable vf function, where free q vectors are not properly handled before queues. This could potentially lead to security vulnerabilities, although the actual impact and attack plausibility have not yet been proven.
Recommendations
For Linux Kernel versions prior to v5.4.162, update to version v5.4.162 or later to resolve the issue. As a temporary workaround, consider restricting access to the iavf disable vf function until a patch is available.
