CVE-2019-11683

Estado: ModificadaCrítica (9.8)—

udp_gro_receive_segment en net/ipv4/udp_offload.c en el kernel de Linux versiones desde la 5.x hasta la 5.0.13 permite a los atacantes remotos causar una denegación de servicio (corrupción de memoria fuera de límites) o posiblemente tener otro impacto no especificado a través de paquetes UDP con una carga útil de 0, debido a un manejo incorrecto de los paquetes de relleno, también conocido como el problema del "GRO packet of death".
