It hex-encodes a key's CKA_ID, which can be up to 64 bytes, into a fixed 128-byte stack buffer. An attacker supplying a malicious PKCS#11 token or module whose key and matching certificate use a 55- to 64-byte CKA_ID can overflow the client's stack during key enumeration, causing a crash.","categories":["Unclassified"],"product":"FreeRDP","vendor":"FreeRDP","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109940","source_modified_at":"2026-10-13T13:56:15.434Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"FreeRDP","vendor":"FreeRDP","versions":[{"version":"3.0.0-beta1","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-2026-109940","source_modified_at":"2026-10-13T13:56:15.434Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"FreeRDP","ecosystem":null},"version":"3.32.0","basis":"first unaffected version stated in the CVE record"}],"cvss":5.1,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00147,"percentile":0.03594,"score_date":"2026-10-23"},"published_at":"2026-10-13T13:27:10.112Z","modified_at":"2026-10-13T13:56:15.434Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-109940","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-13T13:56:15.434Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-109940","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-g8jw-gv54-r94p","tags":["exploit"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/freerdp-3.0.0-beta1-before-3.32.0-stack-buffer-overflow-via-pkcs-11-key-name","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":"2026-10-13T13:55:44.217264Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-13T13:56:15.434Z","content_hash":"1f39e6687882979e4f7f688968f4c0844c08e244e4c413597df633e70db5843f"}}
