Software installed and run as a non-privileged user may conduct improper GPU system calls to trigger NULL pointer dereference kernel exceptions.

Possible memory leak or kernel exceptions caused by reading kernel heap data after free or NULL pointer dereference kernel exception.

Software installed and running inside a Guest VM may conduct improper GPU system calls to prevent other Guests from running work on the GPU.

Software installed and running inside a Guest VM may override Firmware's state and gain access to the GPU.

Possible kernel exceptions caused by reading and writing kernel heap data after free.

Software installed and run as a non-privileged user may conduct improper GPU system calls to subvert GPU HW to write to arbitrary physical memory pages.

Kernel software installed and running inside a Guest VM may exploit memory shared with the GPU Firmware to write data outside the Guest's virtualised GPU memory.

Software installed and run as a non-privileged user may conduct improper GPU system calls to achieve unauthorised reads and writes of physical memory from the GPU HW.

Software installed and run as a non-privileged user may conduct improper GPU system calls to allow unprivileged access to arbitrary physical memory page.

Software installed and run as a non-privileged user may conduct improper GPU system calls to gain access to the graphics buffers of a parent process.
