CVE-2025-56362
Description
A reachable assertion vulnerability exists in the Matter SDK (connectedhomeip) before 1.4.2, specifically within the Level Control cluster's periodic server tick logic. When a MoveToLevel command is sent and immediately followed by a write of OperationMode=2 (in the Pump Configuration and Control cluster), the server tick function violates the assertion `currentLevel < maxLevel`, resulting in a crash. This can be exploited remotely without authentication to cause denial of service. Affected versions include 1.3 and 1.4 (commit ab3d5ae).
