GHSA-3H9P-9PVW-73VM

Vulnerability from github – Published: 2026-05-26 15:32 – Updated: 2026-05-26 15:32

Details

The Security Gateway does not correctly validate a length value in certain IKE packets when NAT-T is used (4500/UDP). As a result, a specially crafted or malformed packet can cause the VPN processing service to terminate unexpectedly, leading to denial of service (temporary interruption of VPN negotiations/traffic).

Severity

8.1 (High)
