Correct BSOD issue #8

Closed ghost closed 1 year ago

ghost commented 1 year ago

I noticed this driver will bugcheck due to an invalid pointer reference. This happens when both nInBufferSize and lpOutBuffer are set to 0 for DeviceIoControl, leading to a buffer not being allocated.

DeviceIoControl(
  hDevice,
  0x9c402000,
  lpInBuffer,
  0,
  lpOutBuffer,
  0,
  lpBytesReturned,
  lpOverlapped);

This happens at in several places throughout the code. I believe I've corrected them all.
