CVE-2025-37920

CVE-2025-37920 affects the Linux kernel in the AF_XDP path. The issue is a race condition in the generic RX path when multiple sockets share the same xsk_buff_pool (shared umem), with RX queues being socket-exclusive and FILL queues sharable. The fix moves the rx_lock from xsk_socket to the share...
