WDDM Fuzzer Allocation- Invalid Param

  • Article

This automated test verifies that kernel-mode drivers are stable when requested to process command buffers that contain invalid data.

The WDDM fuzzer test intercepts command buffers and other private driver data sent from the user-mode driver to the kernel-mode driver. The test randomly modifies the contents of the buffers and private driver data before the data is sent to the kernel. Drivers must not cause the system to crash or stop responding while running this test.
