Vulnerability Title
Integer overflow in TCP_SKB_CB(skb)->tcp_gso_segs
Vulnerability Description
Jonathan Looney discovered that the TCP_SKB_CB(skb)->tcp_gso_segs value was subject to an integer overflow in the Linux kernel when handling TCP Selective Acknowledgments (SACKs). A remote attacker could use this to cause a denial of service.
