CVE-2025-20239Network attack vector

Denial of service via crafted IKEv2 packets

Published Aug 14, 2025 · Updated Aug 14, 2025

A memory leak in Cisco IOS, IOS XE, ASA, and FTD IKEv2 processing allows remote attackers to interrupt VPN and device service. The IKEv2 packet handler fails to release memory after processing crafted packets. Exposure requires IKEv2 to be enabled; IOS and IOS XE devices can reload, while ASA and FTD devices lose memory and new VPN capacity until manually rebooted.
