    nfnetlink_log in netfilter in the Linux kernel before 2.6.20.3 allows attackers to cause a denial of service (crash) via unspecified vectors involving the (1) nfulnl_recv_config function, (2) using "multiple packets per netlink message", and (3) bridged packets, which trigger a NULL pointer dereference.
