Overview

CVE-2025-56365 is a medium-severity vulnerability affecting csa-iot matter. It was published on July 14, 2026 and has a CVSS 3.1 base score of 5.7 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.7, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical 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).

Remediation

Check the references section for vendor advisories and patches from csa-iot. Update matter to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
