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).","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.7},"cwes":["CWE-617"],"references":["https://github.com/project-chip/connectedhomeip/","https://github.com/project-chip/connectedhomeip/issues/37184","https://github.com/project-chip/connectedhomeip/pull/37207","https://github.com/project-chip/connectedhomeip/issues/37184"],"products":["csa-iot:matter"],"source":"nvd","synced_at":"2026-10-19T22:45:36.895656543+00:00"},"epss":{"cve":"CVE-2025-56365","score":0.00284,"percentile":0.20783,"date":"2026-10-26"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
