CVE-2025-56365: Csa-iot matter vulnerability

Csa Iot · Matter

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).
