When the payload length is zero, websocket_reply_pong passes a nullptr stream to websocket_reply_close, triggering an assertion failure that terminates the client process and causes denial of service.","published":"2026-10-16T01:17:40.463Z","modified":"2026-10-20T11:16:56.474885209Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111373.json"},{"type":"ADVISORY","url":"https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-83g2-gf92-5c4g"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-111373"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/freerdp-before-3.32.0-null-dereference-via-zero-length-websocket-ping"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-20T11:16:56.474885209Z"}}
