CVE-2007-1592 (net/ipv6/tcp_ipv6.c in Linux kernel 2.6.x up to 2.6.21-rc3 inadvertently copies the ipv6_fl_socklist from a listening TCP socket to child sockets, which allows local users to cause a denial of service (OOPS) or double-free by opening a listening IPv6 socket, attaching a flow label, and connecting to that socket.)
