La pol\u00edtica define IFLA_PORT_PROFILE como NLA_STRING, IFLA_PORT_INSTANCE_UUID como NLA_BINARY e IFLA_PORT_HOST_UUID como NLA_STRING. Eso significa que la validaci\u00f3n de longitud que utiliza la pol\u00edtica es para el tama\u00f1o m\u00e1ximo de los atributos y no para el tama\u00f1o exacto, por lo que la longitud de estos atributos puede ser menor que los tama\u00f1os que espera enic_set_vf_port. Esto podr\u00eda causar un acceso de lectura fuera de banda en los memcpys de los datos de estos atributos en enic_set_vf_port.\"}],\"metrics\":{},\"references\":[{\"url\":\"https://git.kernel.org/stable/c/25571a12fbc8a1283bd8380d461267956fd426f7\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/2b649d7e0cb42a660f0260ef25fd55fdc9c6c600\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/3c0d36972edbe56fcf98899622d9b90ac9965227\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/7077c22f84f41974a711604a42fd0e0684232ee5\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/aee1955a1509a921c05c70dad5d6fc8563dfcb31\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/ca63fb7af9d3e531aa25f7ae187bfc6c7166ec2d\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/e8021b94b0412c37bcc79027c2e382086b6ce449\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/f6638e955ca00c489894789492776842e102af9c\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"}]}}"
