Summary
driver core: use READ_ONCE() for dev->driver in dev_has_sync_state()
Details

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

driver core: use READ_ONCE() for dev->driver in dev_has_sync_state()

dev_has_sync_state() reads dev->driver twice without holding device_lock() -- once for the NULL check and once to dereference ->sync_state. Some callers only hold device_links_write_lock, which doesn't prevent a concurrent unbind from clearing dev->driver via device_unbind_cleanup().

Fix it by reading dev->driver exactly once with READ_ONCE(), pairing with the WRITE_ONCE() in device_set_driver().
