**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to a potential kernel crash when multiple napi instances redirect to the same AF XDP socket. This can happen when the linked list of sockets to flush gets corrupted by concurrent accesses, leading to a corrupted ring state that can cause a crash when flushing the rings in ` xsk flush()`. The problem is introduced by removing the `queue index` check, allowing multiple napi instances to access the Rx ring at the same time. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
