Red Hat gnome-remote-desktop: denial of service
High7.5CVE-2026-96541 · Published Sep 23, 2026 · updated Sep 24, 2026
A denial-of-service flaw was found in gnome-remote-desktop. An unauthenticated remote attacker can open RDP connections without completing the handshake and retain the connection-throttling slots indefinitely because no pre-authentication handshake deadline is enforced. By exhausting the global connection limit, an attacker can prevent new RDP clients from connecting until a holding socket is closed.
