CVE-2025-21823

CVE-2025-21823 is about batman-adv in the Linux kernel where the unmanaged ELP metric worker was dropped. The issue arose because the ELP worker, which recalculates metrics for neighbors reachable over an interface, used locks that could sleep, conflicting with the RCU list iterator and risking i...
