Cisco IOS XR Distance Vector Multicast Routing Protocol (DVMRP) incorrectly handles Internet Group Management Protocol (IGMP) packets. Exploitation could allow an unauthenticated, remote attacker to immediately crash the IGMP process or make it consume available memory and eventually crash.
Review the upstream advisory, identify the affected product in your inventory, and apply the vendor update when one is available.
Cisco IOS XR Software DVMRP Memory Exhaustion Vulnerability is listed in the HOL Guard supply-chain feed, but affected software is not mapped to a package. Review the upstream advisory for the affected product and vendor guidance. This vulnerability is known to be exploited in the wild.
