            Description

            When a controller establishes an connection with IOCR data lengths in range "1437" to "1440" a buffer overflow occurs resulting in unexpected behavior afterwards. The problem is most likely seen with a firmware with disabled shared device (taglist) during certification testcases Behavior Scenario 7, 8 and 9.
