Description OSIDB Bzimport 2025-05-02 16:05:42 UTC

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

Bluetooth: btsdio: fix use after free bug in btsdio_remove due to unfinished work

In btsdio_probe, &data->work was bound with btsdio_work.In
btsdio_send_frame, it was started by schedule_work.

If we call btsdio_remove with an unfinished job, there may
be a race condition and cause UAF bug on hdev.
