  "title": "watchdog: at91sam9_wdt: prevent timer rearm during teardown",
  "description": "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.",
