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

watchdog: at91sam9_wdt: prevent timer rearm during teardown

at91_ping() rearms the watchdog timer from its callback. timer_delete()

neither waits for a running callback nor prevents it from rearming the

timer, so probe failure or driver removal can leave the timer accessing the

devm-allocated at91wdt after it has been freed.

Use timer_shutdown_sync() on both teardown paths. It waits for a running

callback and rejects any attempt by the callback to rearm the timer. (NVD)
