CVE-2026-48132: VPN service may restart unexpectedly when processing IKE traffic over NAT-T 4500/UDP

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).
