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

Input: byd - synchronize timer deletion before freeing private data

byd_disconnect() uses timer_delete() before freeing the driver's private

data. This does not wait for a running byd_clear_touch() callback, which

dereferences the private data and its psmouse pointer. A callback racing

with disconnect can therefore access the private data after it has been

freed. The timer can also still be re-armed by byd_process_byte() while

the disconnect is in progress.

Use timer_shutdown_sync() before freeing the private data: it waits for

a running callback and turns any later re-arm attempt into a no-op. (NVD)
