Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
watchdog: at91sam9_wdt: prevent timer rearm during teardown<br />
<br />
at91_ping() rearms the watchdog timer from its callback. timer_delete()<br />
neither waits for a running callback nor prevents it from rearming the<br />
timer, so probe failure or driver removal can leave the timer accessing the<br />
devm-allocated at91wdt after it has been freed.<br />
<br />
Use timer_shutdown_sync() on both teardown paths. It waits for a running<br />
callback and rejects any attempt by the callback to rearm the timer.
