En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad:

watchdog: da9063: corrige la gestión de suspensión y reanudación del watchdog con WDOG_HW_RUNNING

da9063_wdt_suspend() y da9063_wdt_resume() solo comprueban watchdog_active(). Cuando el controlador deja el watchdog en ejecución estableciendo WDOG_HW_RUNNING en da9063_wdt_probe(), pero el espacio de usuario nunca abre el dispositivo, WDOG_ACTIVE permanece desactivado y wdt_disable() no se ejecuta en da9063_wdt_suspend. En este caso, la función de retrollamada de suspensión no hace nada y el watchdog sigue contando durante la suspensión del sistema, lo que provoca un reinicio inesperado del sistema. Comprobar WDOG_HW_RUNNING y wdd puede solucionar este problema.
