The code\nunconditionally calls iucv_sock_kill(nsk) in that path.\n\niucv_sock_kill() does not accept a NULL socket pointer and immediately\ndereferences sk via sock_flag(sk, SOCK_ZAPPED). When nsk is NULL,\ncalling iucv_sock_kill(nsk) results in a NULL pointer dereference.\n\nOnly call iucv_sock_kill() when a child socket was successfully\nallocated.",
