## Description

Use-after-free vulnerability in net/ipv4/tcp\_input.c in the Linux kernel
2.6 before 2.6.20, when IPV6\_RECVPKTINFO is set on a listening socket,
allows remote attackers to cause a denial of service (kernel panic) via a
SYN packet while the socket is in a listening (TCP\_LISTEN) state, which is
not properly handled and causes the skb structure to be freed.
