            Description

            When a PPMs CSDU buffer is initialized, a memory overflow occurs when the data length is between 1437 and 1440 byte. As a result, undefined behavior depending on resource configuration and operating situation may occur:

            • The stack may crash
            • The stack might send wrong connect request or response
            • The device stack might stop sending input data to controllers
            • The controller stack might send wrong/inconsistent output data to devices
