In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btsdio: fix use after free bug in btsdio_remove due to race condition
In btsdio_probe, the data->work is bound with btsdio_work. It will be
started in btsdio_send_frame.
If the btsdio_remove runs with a unfinished work, there may be a race
condition that hdev is freed but used in btsdio_work. Fix it by
canceling the work before do cleanup in btsdio_remove.
