Se ha encontrado una vulnerabilidad en el kernel de Linux, en la que un uso de memoria previamente liberada en el manejador postclose() de nouveau podría ocurrir si se quita el dispositivo (que no es común quitar la tarjeta de vídeo físicamente sin apagar, pero lo mismo ocurre si se "desvincula" el controlador)
