CVE-2026-96541

Gnome-remote-desktop: gnome-remote-desktop: unauthenticated rdp sockets lack a handshake deadline

CVSS 3.1 7.5 HIGHCheck source for fixed versionsKEV status unknown
Original advisory

cve-program · CVE-2026-96541

Published

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.
