✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 Workaround: If system-mode RDP is not required, disable it. If it must remain enabled, restrict the RDP listener (default port 3389) to trusted hosts or management networks using host-based firewall rules.
