In the Linux kernel, the following vulnerability has been resolved:

vduse: Fix race in vduse_dev_msg_sync and vduse_dev_read_iter

There is one race case in vduse_dev_msg_sync and vduse_dev_read_iter:

vduse_dev_read_iter():
    lock(msg_lock);
    dequeue_msg(send_list);
    unlock(msg_lock);
vduse_dev_msg_sync():
    wait_timeout() finish
    lock(msg_lock);
    check msg->complete is false
        list_del(msg);   <- double list_del() crash!

To fix this case, we shall ensure vduse_msg is on send_list or recv_list
outside the msg_lock critical section.
