Exploit públicoNo conocidosin código público localizado

La función tpacket_rcv en net/packet/af_packet.c en el kernel de Linux en versiones anteriores a la 4.13 no gestiona correctamente cabeceras vnet, lo que podría permitir que usuarios locales provoquen una denegación de servicio (desbordamiento de búfer y corrupción de disco y de memoria) o, posiblemente, provoquen otro impacto sin especificar mediante llamadas del sistema manipuladas.
