Name of the Vulnerable Software and Affected Versions Linux Kernel versions prior to v5.10.71

Description A potential issue exists in the Linux Kernel, specifically in the flower scheduler. The problem is related to the fl walk() function, which is not properly protected with RCU. This issue was introduced in version v5.3 and is fixed in version v5.10.71. The actual impact and attack plausibility have not yet been proven.

Recommendations For Linux Kernel versions prior to v5.10.71, update to version v5.10.71 or later to resolve the issue. As a temporary workaround, consider implementing additional protection mechanisms for the fl walk() function until a patch is applied.
