### Description

A vulnerability in the OSPF version 2 (OSPFv2) feature of Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause an affected device to reload unexpectedly, resulting in a denial of service (DoS) condition. This vulnerability is due to improper validation of OSPF updates that are processed by a device. An attacker could exploit this vulnerability by sending a malformed OSPF update to the device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition.
