{"id":"CVE-2025-56362","details":"A reachable assertion vulnerability exists in the Matter SDK (connectedhomeip) before 1.4.2, specifically within the Level Control cluster's periodic server tick logic. When a MoveToLevel command is sent and immediately followed by a write of OperationMode=2 (in the Pump Configuration and Control cluster), the server tick function violates the assertion `currentLevel \u003c maxLevel`, resulting in a crash. This can be exploited remotely without authentication to cause denial of service. Affected versions include 1.3 and 1.4 (commit ab3d5ae).","modified":"2026-07-18T03:45:31.445921783Z","published":"2026-07-14T00:00:00Z","database_specific":{"cna_assigner":"mitre","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/56xxx/CVE-2025-56362.json"},"references":[{"type":"WEB","url":"https://github.com/project-chip/connectedhomeip/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/56xxx/CVE-2025-56362.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-56362"},{"type":"REPORT","url":"https://github.com/project-chip/connectedhomeip/issues/38618"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/project-chip/connectedhomeip","events":[{"introduced":"5bb5c9e23d532cea40476fc0bd1d3008522792ba"},{"fixed":"871b4347b3b068dc161d6a02f867a0335cff13ed"}],"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":"0"},{"fixed":"1.4.2"},{"introduced":"1.3.0.0"},{"last_affected":"1.3.0.0"},{"introduced":"1.4.0.0"},{"last_affected":"1.4.0.0"}],"source":["DESCRIPTION","CPE_STRING"]}}],"versions":["1.3.0.0","1.4.0.0","v1.3.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-56362.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
