Overview

github.com/cilium/cilium/pkg/bpf is an eBPF-based Networking, Security, and Observability

Affected versions of this package are vulnerable to Access Control Bypass when IPv6 traffic is sent from a Cilium-managed pod to the host-network namespace. If IPv4, IPv6, and endpoint routes are in use, and the host firewall is enabled (which it is not by default), host policy enforcement can be bypassed.
