The icmp6_send function in net/ipv6/icmp.c in the Linux kernel through 4.8.12 omits a certain check of the dst data structure, which allows remote attackers to cause a denial of service (panic) via a fragmented IPv6 packet. |

| Notes |

The issue was introduced in 4.8.10 by 5d41ce29e ("net: icmp6_send should use dst dev to determine L3 domain") and fixed in trunk by 79dc7e3f1cd323be4c81aa1a94faa1b3ed987fb2 ("net: handle no dst on skb in icmp6_send"). |
