What is CVE-2026-18358?

A vulnerability exists in the gnome-remote-desktop component of Red Hat Enterprise Linux, where the connection handler fails to throttle incoming connections when RDP is enabled. This oversight allows unauthenticated attackers to initiate multiple pre-authentication connections, potentially leading to resource exhaustion. As a result, legitimate users may encounter difficulties in establishing RDP sessions, as the system becomes overwhelmed by the accumulation of accepted sockets and pending routing operations.
