In standard Red Hat Enterprise Linux deployments, NFSv4 is used by default, eliminating reliance on rpc.statd for file lock monitoring. Furthermore, default firewall policies block incoming remote procedure call traffic from untrusted networks, restricting exposure primarily to legacy NFSv3 configurations that accept remote traffic from unverified sources.", "threat_severity": "Moderate"}
