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

Bluetooth: Fix race condition in hidp_session_thread

There is a potential race condition in hidp_session_thread that may lead to use-after-free. For instance, the timer is active while hidp_del_timer is called in hidp_session_thread(). After hidp_session_put, then 'session' will be freed, causing kernel panic when hidp_idle_timeout is running.

The solution is to use del_timer_sync instead of del_timer.

Here is the call trace:
