No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

A null pointer dereference vulnerability in WatchGuard Fireware OS may allow a remote unauthenticated attacker to create a denial-of-service (DoS) condition by sending specially crafted IKEv2 messages. This vulnerability affects both the Mobile User VPN with IKEv2 and the Branch Office VPN using IKEv2 when configured with a dynamic gateway peer.

This vulnerability affects Fireware OS 11.10.2 up to and including 11.12.4_Update1, 12.0 up to and including 12.12 and 2025.1 up to and including 2026.2
