Exploit públicoNo conocidosin código público localizado

función __skb_flow_dissect en net/core/flow_dissector.c en el kernel Linux en versiones anteriores a la 4.3 no garantiza que se inicialicen n_proto, ip_proto y thoff. Esto permite que atacantes remotos provoquen una denegación de servicio (bloqueo del sistema) o que ejecuten código arbitrario mediante un único paquete MPLS manipulado.
