Summary
  • (es) La implementación de IPv6 en el kernel de Linux anterior a 6.3 tiene un umbral net/ipv6/route.c max_size que se puede consumir fácilmente, por ejemplo, provocando una denegación de servicio (errores de red inaccesible) cuando los paquetes IPv6 se envían en un bucle a través de un enchufe crudo.
