CVE-2025-30162: Cilium East-west traffic not subject to egress policy enforcement for requests via Gateway API load balancers

For Cilium users who:

• Use Gateway API for Ingress for some services AND
• Use LB-IPAM or BGP for LB Service implementation AND
• Use network policies to block egress traffic from workloads in a namespace to workloads in other namespaces

Egress traffic from workloads covered by such network policies to LoadBalancers configured by Gateway resources will incorrectly be allowed.

LoadBalancer resources not deployed via a Gateway API configuration are not affected by this issue.
