            Description

            When a controller connects with the device and tries to use 1437 to 1440 byte output data length a memory corruption occurs. This may result in unexpected firmware behavior including firmware crash.

            If a device application supports shared device function and not all AR resources are in use by Profinet IO Controller in the current configuration, an attacker may send a corresponding Connect.req service to the device and cause a malfunction.
