Full vulnerability record from the local CVENow database.
Description
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.

En btsdio_probe, el trabajo data->work está enlazado con btsdio_work. Se iniciará en btsdio_send_frame. Si btsdio_remove se ejecuta con un trabajo sin terminar, puede existir una condición de carrera que indique que hdev se libera, pero se usa en btsdio_work. Para solucionarlo, cancele el trabajo antes de realizar la limpieza en btsdio_remove."
