{"id":"CVE-2026-44640","summary":"NanoMQ: QUIC Dialer Close Type Confusion","details":"NanoMQ MQTT Broker (NanoMQ) is an all-around Edge Messaging Platform. Prior to 0.24.14, aio-\u003eprov_data is stored as nni_quic_conn* during dialing, but read as ex_quic_conn* during dialer close. This type confusion causes invalid object interpretation and leads to close-path hang/crash behavior. This vulnerability is fixed in 0.24.14.","aliases":["GHSA-9fgw-v323-jmjj"],"modified":"2026-08-04T11:50:59.365430872Z","published":"2026-05-29T19:28:47.185Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44640.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-843"]},"references":[{"type":"WEB","url":"https://github.com/nanomq/nanomq/releases/tag/0.24.14"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44640.json"},{"type":"ADVISORY","url":"https://github.com/nanomq/nanomq/security/advisories/GHSA-9fgw-v323-jmjj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44640"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nanomq/nanomq","events":[{"introduced":"0"},{"fixed":"16bdb38921e7bbeab887cf229c2eb145889dfa88"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.24.14"}],"source":"AFFECTED_FIELD"}}],"versions":["0.24.13","0.24.12","0.24.11","0.24.10","0.24.9","0.24.8","0.24.7","0.24.6","0.24.5","0.24.4","0.24.3-5","0.24.3","0.24.2","0.24.1","0.24.0","0.23.10","0.23.9","0.23.8","0.23.7-11","0.23.7","0.23.6","0.23.5","0.23.4","0.23.3","0.23.2","0.23.1","0.23.0","0.22.10","0.22.8","0.22.7","0.22.6","0.22.2","0.22.3","0.22.1","0.22.0","0.21.10","0.21.9","0.21.8","0.21.7","0.21.6","0.21.5","0.21.2","0.21.1","0.21","0.20.8","0.20.6","0.20.5","0.20.0","0.19.5","0.19.1","0.19.0","0.18.2","0.18.1","0.17.8","0.17.5","0.17.2","0.16.5","0.16.3","0.16.2","0.16.0","0.15.5","0.15.3","0.15.2","0.15.1","0.15.0","0.14.8","0.14.5","0.12.1","0.14.1","0.14.0","0.13.8","0.13.6","0.13.0","0.12.5","0.12.2","0.12.0","0.11.82","0.11.8","0.11.5","0.11.3","0.11.2","0.11.0","0.10.8","0.10.5","0.10.1","0.9.7","0.9.5","0.9.2","0.9.0","0.8.6log","0.8.5","0.8.3","0.8.0","0.7.9","0.7.8","0.7.5","0.7.5rc","0.7.4rc","0.7.4","0.7.3","0.7.2","0.6.8","0.7.0","0.6.7rc","0.6.4","0.6.3","0.6.2","0.6.0","0.5.9","0.5.8","0.5.5","0.5.2","0.5.0","0.4.8","0.4.5","0.4.3","0.4.2","0.4.1","0.4.0","0.3.8","0.3.5","0.3.4","0.3.3","0.3.2","0.3.0","0.2.5","0.2.2","0.2.1","0.2.0","0.1.0","0.0.3","0.0.2","0.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-44640.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:L"}]}
