CVE-2026-20012Network attack vector

Denial of service via crafted IKEv2 packets

Published Mar 25, 2026 · Updated Mar 25, 2026

Improper IKEv2 packet parsing in Cisco IOS, IOS XE, Secure Firewall ASA, and Secure FTD allows remote attackers to cause denial of service. The IKEv2 parser mishandles crafted packets and fails to release memory allocated while processing them, allowing repeated requests to consume device memory. Exposure requires the IKEv2 VPN feature to be enabled; IOS and IOS XE devices reload, while ASA and FTD lose memory and can reject new VPN sessions until reboot.
