According to its self-reported version, Cisco IOS-XE Software is affected by a vulnerability.

  - A vulnerability in the Intermediate System-to-Intermediate System (IS-IS) protocol of Cisco IOS Software     and Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause a denial of service     (DoS) condition on an affected device. This vulnerability is due to insufficient input validation when     parsing an ingress IS-IS packet. An attacker could exploit this vulnerability by sending a crafted IS-IS     packet to an affected device after forming an adjacency. A successful exploit could allow the attacker to     cause the affected device to reload, resulting in a denial of service (DoS) condition. Note: The IS-IS     protocol is a routing protocol. To exploit this vulnerability, an attacker must be Layer 2-adjacent to the     affected device and have formed an adjacency. (CVE-2024-20312)
