Exploit públicoNo conocidosin código público localizado
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad:
net: xfrm: rechazar cabeceras de transporte espintcp no representables
ESP-in-TCP puede entregar paquetes xfrm cuyo desplazamiento de la cabecera de transporte deja de caber tras el análisis del flujo que recorta la envoltura TCP. El reinicio simple de la cabecera de transporte trunca ese desplazamiento y activa la ruta de advertencia de skb.
Usar el auxiliar cuidadoso de cabecera de transporte y descartar el skb a través de la ruta de error XFRM existente cuando el desplazamiento no puede representarse.
