  "details": "In the Linux kernel, the following vulnerability has been resolved:  driver core: use READ_ONCE() for dev-\u003edriver in dev_has_sync_state()  dev_has_sync_state() reads dev-\u003edriver twice without holding device_lock() -- once for the NULL check and once to dereference -\u003esync_state. Some callers only hold device_links_write_lock, which doesn't prevent a concurrent unbind from clearing dev-\u003edriver via device_unbind_cleanup().  Fix it by reading dev-\u003edriver exactly once with READ_ONCE(), pairing with the WRITE_ONCE() in device_set_driver().",
