In the Linux kernel, the following vulnerability has been resolved: fou: Don't allow 0 for FOU_ATTR_IPPROTO. fou_udp_recv() has the same problem mentioned in the previous patch. If FOU_ATTR_IPPROTO is set to 0, skb is not freed by fou_udp_recv() nor "resubmit"-ted in ip_protocol_deliver_rcu(). Let's forbid 0 for FOU_ATTR_IPPROTO.
En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: fou: No permitir 0 para FOU_ATTR_IPPROTO. fou_udp_recv() tiene el mismo problema mencionado en el parche anterior. Si FOU_ATTR_IPPROTO se establece en 0, skb no es liberado por fou_udp_recv() ni 'reenviado' en ip_protocol_deliver_rcu(). Prohibamos 0 para FOU_ATTR_IPPROTO.
