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.

Security readout for executives and security teams

CVE-2014-2309 is a Linux kernel IPv6 denial-of-service issue. A flood of ICMPv6 Router Advertisement packets can make affected kernels consume memory because route additions are counted incorrectly. The known impact is availability loss, not data theft or code execution. Likely exposure is Linux systems running kernels through 3.13.6 with IPv6 Router Advertisement processing reachable. Internet-wide exposure is unclear from the provided sources, and affected distribution backports are not fully enumerated. Treat this as a targeted availability risk for legacy Linux infrastructure. Prioritize externally or broadly reachable IPv6 systems, network appliances, and hosts where downtime has business impact. Mitigation focus: Upgrade to a vendor-supported kernel containing the referenced IPv6 route accounting fix.; Review SUSE/openSUSE or relevant distribution advisories for backported fixed packages.; Limit unauthorized ICMPv6 Router Advertisement traffic where operationally appropriate..
