For IPv6 over IPv4 tunnel device - Simple Internet Transition (SIT), an exploitable remote memory leak happens when pskb_may_pull() fails in function ipip6_rcv() in net/ipv6/sit.c.

Memory leak in the ipip6_rcv function in net/ipv6/sit.c in the Linux kernel before 2.6.25.3 allows remote attackers to cause a denial of service (memory consumption) via network traffic to a Simple Internet Transition (SIT) tunnel interface, related to the pskb_may_pull and kfree_skb functions, and management of an skb reference count.
