Description

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

The ip6_sk_dst_check function in net/ipv6/ip6_output.c in the Linux kernel before 3.10 allows local users to cause a denial of service (system crash) by using an AF_INET6 socket for a connection to an IPv4 interface.
