Dispositivo USB, en particular: - La matriz de metadatos (hdr_off..hdr_off+2*pkt_cnt) puede estar fuera de los l\u00edmites, provocando lecturas OOB y (en sistemas big-endian) cambios de endianidad OOB. - Un paquete puede superponerse a la matriz de metadatos, lo que provoca un cambio de endianidad OOB posterior que corrompe los datos utilizados por un SKB clonado que ya se ha transferido a la pila de red. - Se puede construir un paquete SKB cuya cola est\u00e9 mucho m\u00e1s all\u00e1 de su extremo, lo que hace que los datos del mont\u00f3n fuera de los l\u00edmites se consideren parte de los datos del SKB. He probado que esto puede ser utilizado por un dispositivo USB malicioso para enviar una solicitud de eco ICMPv6 falsa y recibir una respuesta de eco ICMPv6 en respuesta que contiene datos aleatorios del mont\u00f3n del kernel.
