CVE-2025-5024Network attack vector

Unauthenticated service crashes via RDP connection floods

Published May 22, 2025 · Updated Jun 30, 2026

Denial of service in gnome-remote-desktop on affected Red Hat Enterprise Linux releases allows remote attackers to crash the RDP service. The RDP listener accepts rapid unauthenticated connections carrying malformed PDUs without effective throttling, leaking file descriptors until the process reaches its open-file limit and aborts. The service must be listening for RDP, and sustained attacks can leave it unable to open files even after systemd restarts it.
