The ip6_route_add function in net/ipv6/route.c in the Linux kernel through 3.13.6 does not properly count the addition of routes, which allows remote attackers to cause a denial of service (memory consumption) via a flood of ICMPv6 Router Advertisement packets.
CVSS Severity (version 2.0):
Impact Subscore: 6.9
Exploitability Subscore: 6.5
CVSS Version 2 Metrics:
Access Vector: Local network exploitable
Access Complexity: Low
Authentication: Not required to exploit
Impact Type: Allows disruption of service
