            Description

            This problem is related to the cifX Toolkit, which includes HWIF functions, not checking unalinged memory access to the DPM in case of accesing single 16Bit or 32Bit value (HWIF_READ16 / WRITE16, HWIF_READ32 / WRITE32).
            This will overwrite DPM data before and after the addressed payload data.
