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.","state":0,"publishedAt":"2026-10-13T13:27:10.112+00:00","modifiedAt":"2026-10-13T13:56:15.434+00:00","affected":[{"ecosystem":"Vendor product","name":"FreeRDP","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"FreeRDP\",\n                    \"product\": \"FreeRDP\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"3.0.0-beta1\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"3.32.0\"\n                        },\n                        {\n                            \"version\": \"3.32.0\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":5.1,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","score":4.3,"severity":"MEDIUM"}],"references":["https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-g8jw-gv54-r94p","https://www.vulncheck.com/advisories/freerdp-3.0.0-beta1-before-3.32.0-stack-buffer-overflow-via-pkcs-11-key-name"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-109940","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-109940","identifiers":["CVE-2026-109940"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
