Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

A vulnerability in the Autonomic Networking feature of Cisco IOS Software and Cisco IOS XE Software can be triggered to force autonomic nodes to reload. The flaw affects the releases Denali-16.2.1 and Denali-16.3.1 and is tracked as CSCvd88936. Its CVSS 3.1 base score is 6.5, reflecting an attack that requires only adjacent network access and no authentication or user interaction.
