Summaryinfo

A vulnerability categorized as problematic has been discovered in Matter SDK up to 1.3.9. This vulnerability affects the function Invoke of the component Interaction Model Command Processing. Such manipulation of the argument endpoint/cluster leads to assertion. This vulnerability is traded as CVE-2025-56365. The attack may be launched remotely. There is no exploit available.

Detailsinfo

A vulnerability was found in Matter SDK up to 1.3.9 and classified as problematic. Affected by this issue is the function Invoke of the component Interaction Model Command Processing. The manipulation of the argument endpoint/cluster with an unknown input leads to a assertion vulnerability. Using CWE to declare the problem leads to CWE-617. The product contains an assert() or similar statement that can be triggered by an attacker, which leads to an application exit or other behavior that is more severe than necessary. Impacted is availability. CVE summarizes:

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).

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2025-56365 since 08/16/2025. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. There are known technical details, but no exploit is available.

Upgrading to version 1.4.0 eliminates this vulnerability.
