A vulnerability in the Open Shortest Path First version 3 (OSPFv3) implementation in Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause a crash of the OSPFv3 process on an affected device.

The vulnerability is due to improper parsing of malformed type 1 link-state advertisement (LSA) packets.

An exploit could allow the attacker to cause a crash of the OSPFv3 process on an affected device, which may lead to a denial of service (DoS) condition.
