{"id":"CVE-2025-56365","url":"https://www.cyber-defence.io/tools/cve/CVE-2025-56365","generatedAt":"2026-10-28T03:26:20.896Z","title":"A reachable assertion vulnerability exists in the Matter SDK (connectedhomeip) before 1.4.0, in the interaction model command processing logic.","description":"A reachable assertion vulnerability exists in the Matter SDK (connectedhomeip) before 1.4.0, in the interaction model command processing logic. When an InvokeCommandRequest is sent to a nonexistent endpoint and cluster (e.g., 0x34), the code incorrectly treats the endpoint as valid due to missing checks in CodegenDataModelProvider::Invoke. This causes a VerifyOrDie failure in ProcessCommandDataIB and results in a crash (SIGABRT). The issue has been acknowledged and fixed in a later revision (PR #37207).","published":"2026-07-14T23:17:28.000Z","lastModified":"2026-10-13T09:10:00.000Z","status":"Analyzed","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":5.7,"severity":"MEDIUM","vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-617"],"affected":["csa-iot/matter"],"epss":{"score":0.00284,"percentile":0.20783,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.28%).
