            Description

            When the CPM is configured for C_SDU lengths of 1437 to 1440 byte, a buffer overflow occurs. As a consequence unexpected firmware behavior of any kind occurs.

            The problem affects all Profinet Device firmware and can be triggered by Profinet IO Controller with sending a Connect with an Output IOCR data length of 1437 to 1440 byte.

            The Profinet IO Controller is not affected since it uses a different data path.
