Pero luego, después de la llamada a pn533_poll_create_mod_list() en pn533_start_poll(), la lista de mod de sondeo permanecerá vacía y dev-&gt;poll_mod_count permanecerá en 0, lo que conduce a la división por cero. Normalmente, ningún protocolo im tiene el valor 1 en la máscara, por lo que el controlador no espera esta combinación. Pero estos valores de protocolo en realidad provienen del espacio de usuario a través de la interfaz Netlink (operación NFC_CMD_START_POLL). Por lo tanto, un programa dañado o malicioso puede enviar un mensaje que contenga una combinación \"mala\" de valores de parámetros de protocolo, de modo que dev-&gt;poll_mod_count no se incremente dentro de pn533_poll_create_mod_list(), lo que lleva a una división por cero.
