CVE-2025-5024: Gnome-remote-desktop: uncontrolled resource consumption due to malformed rdp pdus
A flaw was found in gnome-remote-desktop. Once gnome-remote-desktop listens for RDP connections, an unauthenticated attacker can exhaust system resources and repeatedly crash the process. There may be a resource leak after many attacks, which will also result in gnome-remote-desktop no longer being able to open files even after it is restarted via systemd.
Security readout for executives and security teams
Plain-English summary
CVE-2025-5024 can let an unauthenticated remote party crash GNOME Remote Desktop when RDP is enabled. The main business impact is loss of remote desktop availability, with possible lingering file-handle exhaustion after repeated attacks. It does not indicate data theft or code execution in the provided sources.
Executive priority
Treat as a high-priority availability risk for exposed Linux desktop and remote-access environments. Patch or disable reachable RDP services promptly, especially where remote desktop availability supports operations, administration, or customer-facing support.
Technical view
Malformed RDP protocol data units can trigger uncontrolled resource consumption in gnome-remote-desktop. The vulnerability is network reachable when the service listens for RDP connections, requires no attacker privileges, and affects availability only. Red Hat rates it High with CVSS 7.4 and CWE-400.
Likely exposure
Exposure is likely limited to affected Red Hat Enterprise Linux 8, 9, and 10 systems with gnome-remote-desktop installed and RDP enabled or reachable. Desktop, VDI, admin workstation, and jump-host use cases should be prioritized over systems without GNOME Remote Desktop listening.
Exploitation context
The bundle does not show CISA KEV listing or cited evidence of active exploitation. The described attack path is unauthenticated and network-based once RDP listening is enabled, but the provided sources do not include exploit availability, proof-of-concept details, or observed attacks.
Researcher notes
The key constraint is exposure state: the package alone is not enough; RDP listening matters. The CVSS vector includes UI:R, but the description frames attackability after the service is enabled. Sources do not provide exploit artifacts or full root-cause detail beyond malformed RDP PDUs and resource leakage.
Mitigation direction
Apply the relevant Red Hat RHSA update for the installed RHEL stream and package.
Disable gnome-remote-desktop or RDP where remote desktop access is not required.
Restrict RDP access to trusted VPN, management networks, or approved source addresses.
Follow Red Hat guidance for restart or reboot requirements after package updates.
Monitor affected hosts for repeated service crashes or file exhaustion symptoms.
Validation and detection
Inventory RHEL 8, 9, and 10 systems with the gnome-remote-desktop package installed.
Confirm whether GNOME Remote Desktop is configured to listen for RDP connections.
Map installed package versions to the affected versions listed in the CVE bundle.
Verify applicable RHSA updates are installed for each affected RHEL lifecycle stream.
Review service logs for repeated crashes around remote desktop connection attempts.

Uncontrolled Resource Consumption
Uncontrolled Resource Consumption represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
