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.","epss":{"date":"2026-11-03","percentile":0.60095,"score":0.00913},"exploits":[{"kind":"exploit","source":"ADP: CISA-ADP","url":"https://gitlab.gnome.org/GNOME/gnome-remote-desktop/-/issues/356"}],"kev":null,"metrics":[{"score":7.5,"severity":"high","source":"CNA: redhat","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},{"score":7.5,"severity":"high","source":"NVD: secalert@redhat.com","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"}],"modifiedAt":1793747880723,"publishedAt":1790186903661,"references":[{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-96541"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2539385"},{"source":"CNA: redhat","tags":[],"url":"https://gitlab.gnome.org/GNOME/gnome-remote-desktop/-/issues/356"},{"source":"ADP: CISA-ADP","tags":["exploit"],"url":"https://gitlab.gnome.org/GNOME/gnome-remote-desktop/-/issues/356"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/security/cve/CVE-2026-96541"},{"source":"secalert@redhat.com","tags":[],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2539385"},{"source":"secalert@redhat.com","tags":[],"url":"https://gitlab.gnome.org/GNOME/gnome-remote-desktop/-/issues/356"},{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","tags":[],"url":"https://gitlab.gnome.org/GNOME/gnome-remote-desktop/-/issues/356"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"Disable the RDP listener when it is not required, or restrict access to the RDP port to trusted networks or hosts at the network boundary.
