In Cilium, packets from terminating endpoints may not be encrypted in Wireguard-enabled clusters

Impact When using Wireguard transparent encryption in a Cilium cluster, packets that originate from a terminating endpoint can leave the source node without encryption due to a race condition in how traffic is processed by Cilium. Patches This issue has been patched in...
