GPU DDK - UAF read and/or write to arbitrary physical pages in DevmemIntChangeSparse due to incorrect calculation of the virtual index count

Software installed and run as a non-privileged user may conduct improper GPU system calls to cause mismanagement of a mapping state maintained for a sparse memory allocation. The product accidentally refers to the wrong memory due to the semantics of how math operations are implicitly scaled across buffers of different sizes.

GPU DDK - ui64RobustnessAddress can overwrite Freelist / HWRT (and bypass PMMETA)

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. Under certain circumstances this exploit could be used to corrupt data pages not allocated by the GPU driver but memory pages in use by the kernel and drivers running on the platform altering their behaviour.
