A malicious or compromised RDP server can terminate a connected FreeRDP client after RDPGFX AVC444 negotiation by sending an in-bounds region rectangle with an odd width.","categories":["Unclassified"],"product":"FreeRDP","vendor":"FreeRDP","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109946","source_modified_at":"2026-10-18T12:08:53.452Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"FreeRDP","vendor":"FreeRDP","versions":[{"version":"3.11.0","status":"affected","versionType":"semver","lessThan":"3.32.0"},{"version":"3.32.0","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109946","source_modified_at":"2026-10-18T12:08:53.452Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"FreeRDP","ecosystem":null},"version":"3.32.0","basis":"first unaffected version stated in the CVE record"}],"cvss":7.1,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00285,"percentile":0.1997,"score_date":"2026-10-23"},"published_at":"2026-10-13T13:27:13.792Z","modified_at":"2026-10-18T12:08:53.452Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-109946","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-18T12:08:53.452Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-109946","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-97pf-pwp3-2wrv","tags":["exploit"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/freerdp-3.11.0-before-3.32.0-reachable-assertion-via-avc444-odd-region-width","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-18T12:08:50.525886Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-18T12:08:53.452Z","content_hash":"7d988ceff2b446966f27a1a28cd38fb00b10f901b07934664cbced56a56b1a85"}}
