MemAfterReqCompletedRead rule (kmdf)
The MemAfterReqCompletedRead rule specifies that within the EvtIoRead callback function, the framework memory object cannot be accessed after the I/O request is completed.
Within the driver's EvtIoRead callback function, the framework memory object that was retrieved by calling the WdfRequestRetrieveOutputMemory method cannot be accessed after calling WdfRequestComplete, WdfRequestCompleteWithInformation, or WdfRequestCompleteWithPriorityBoost on the I/O request.
This rule considers the following two memory access methods:
