Description: 
 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.
Ubuntu-Description: 
 Masayuki Nakagawa discovered an error in the flowlabel handling of
 IPv6 network sockets. A local attacker could exploit this to crash
 the kernel.
