CVE-2025-56365: n/a
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).
AI Analysis
Technical Summary
The Matter SDK (connectedhomeip) before version 1.4.0 contains a vulnerability in the interaction model command processing logic. Specifically, when an InvokeCommandRequest is sent to a nonexistent endpoint and cluster (e.g., cluster 0x34), the CodegenDataModelProvider::Invoke function fails to properly validate the endpoint. This leads to a VerifyOrDie assertion failure in ProcessCommandDataIB, resulting in a process crash (SIGABRT). The issue has been fixed in a later revision as indicated by pull request #37207.
Potential Impact
This vulnerability causes the affected software to crash when processing specially crafted InvokeCommandRequest messages targeting nonexistent endpoints and clusters. The crash results from an assertion failure, leading to denial of service conditions. There is no indication of code execution or data corruption beyond the crash. No known exploits are reported in the wild.
Mitigation Recommendations
A fix for this vulnerability has been implemented in a later revision of the Matter SDK after version 1.4.0 (PR #37207). Users should upgrade to version 1.4.0 or later to remediate this issue. Patch status is not explicitly confirmed in the advisory, but the fix is acknowledged. Until upgrading, avoid sending InvokeCommandRequest messages to nonexistent endpoints and clusters.
