CVE-2025-56361
Matter SDK Level Control Cluster Denial of Service Vulnerability
Description
A reachable assertion vulnerability exists in the Matter SDK (connectedhomeip) 1.3 thru 1.4, specifically within the Level Control cluster's server tick logic (`emberAfLevelControlClusterServerTickCallback`). When a MoveToLevel command is executed and followed by a conflicting write to the OperationMode attribute (in the Pump Configuration and Control cluster), an invariant check (`minLevel < currentLevel`) fails and causes the device to abort. This leads to a denial of service condition. The issue is confirmed in SDK versions 1.3 and 1.4 (commit ab3d5ae), and is triggered remotely without authentication.

Action Type Old Value New Value Added Translation Title: Matter SDK, Description: Una vulnerabilidad de aserción alcanzable existe en el Matter SDK (connectedhomeip) 1.3 hasta 1.4, específicamente dentro de la lógica de 'tick' del servidor del clúster de Control de Nivel ('emberAfLevelControlClusterServerTickCallback'). Cuando se ejecuta un comando MoveToLevel y es seguido por una escritura conflictiva al atributo OperationMode (en el clúster de Configuración y Control de Bomba), una verificación de invariante ('minLevel menor que currentLevel') falla y causa que el dispositivo aborte. Esto lleva a una condición de denegación de servicio. El problema está confirmado en las versiones del SDK 1.3 y 1.4 (commit ab3d5ae), y se activa remotamente sin autenticación. -
