In the Linux kernel, the following vulnerability has been resolved:
watchdog: cpu5wdt.c: Fix use-after-free bug caused by cpu5wdt_trigger
When the cpu5wdt module is removing, the origin code uses del_timer() to
de-activate the timer. If the timer handler is running, del_timer() could
not stop it and will return directly. If the port region is released by
release_region() and then the timer handler cpu5wdt_trigger() calls outb()
to write into the region that is released, the use-after-free bug will
happen.
Change del_timer() to timer_shutdown_sync() in order that the timer handler
could be finished before the port region is released.
