{"id":"CVE-2025-56361","details":"A reachable assertion vulnerability exists in the Matter SDK (connectedhomeip) 1.3 thru 1.4, specifically within the Level Control cluster's server tick logic (`emberAfLevelControlClusterServerTickCallback`). When a MoveToLevel command is executed and followed by a conflicting write to the OperationMode attribute (in the Pump Configuration and Control cluster), an invariant check (`minLevel \u003c currentLevel`) fails and causes the device to abort. This leads to a denial of service condition. The issue is confirmed in SDK versions 1.3 and 1.4 (commit ab3d5ae), and is triggered remotely without authentication.","modified":"2026-08-12T03:51:35.671483832Z","published":"2026-07-14T00:00:00Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/56xxx/CVE-2025-56361.json","cna_assigner":"mitre"},"references":[{"type":"WEB","url":"https://github.com/project-chip/connectedhomeip/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/56xxx/CVE-2025-56361.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-56361"},{"type":"REPORT","url":"https://github.com/project-chip/connectedhomeip/issues/38619"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/project-chip/connectedhomeip","events":[{"introduced":"5bb5c9e23d532cea40476fc0bd1d3008522792ba"},{"last_affected":"43aa98c2d30ee547c6b587b9de7bbb794f175ece"}],"database_specific":{"cpe":["cpe:2.3:a:csa-iot:matter:1.3.0.0:*:*:*:*:*:*:*","cpe:2.3:a:csa-iot:matter:1.4.0.0:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"1.3.0.0"},{"last_affected":"1.3.0.0"},{"introduced":"1.4.0.0"},{"last_affected":"1.4.0.0"}],"source":"CPE_STRING"}}],"versions":["1.3.0.0","1.4.0.0","v1.4.0.0","v1.3.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-56361.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
