Answer
Pods share node network namespace, risking port conflicts and weaker isolation.
Quick Answer
hostNetwork: true puts the Pod directly on the host's network namespace — no isolation. The Pod sees and can reach everything the host sees. Multiple Pods on the same node can't use the same port. If compromised, the attacker has direct network access to the host environment. Only justified for very specific system-level network workloads.
