    Mitigation guidance
    • To mitigate this issue, restrict network access to the pmproxy service (port 44322/TCP) to trusted hosts only using firewall rules. If pmproxy functionality is not required, disable the service. Disabling the service will prevent remote access to performance metrics via pmproxy. To disable the service, run: `sudo systemctl stop pmproxy` and `sudo systemctl disable pmproxy`. If firewalling, ensure to reload the firewall rules after making changes.
