AI-suggested
Red Hat has released security updates for gnome-remote-desktop in Red Hat Enterprise Linux 10 to address this vulnerability. Applying the official patches as described in Red Hat Advisory RHSA-2026:98622 will remediate the issue by enforcing a handshake deadline on unauthenticated RDP sockets. Users should follow the update instructions at https://access.redhat.com/articles/11258 to apply the fix. No additional mitigation is required once the update is applied.
Description
A denial-of-service vulnerability exists in gnome-remote-desktop where an unauthenticated remote attacker can open RDP connections without completing the handshake and hold connection slots indefinitely. This exhausts the global connection limit, preventing new RDP clients from connecting until the held sockets are closed. The issue is due to the lack of a handshake deadline enforcement on pre-authentication RDP sockets.
