Title
GPU DDK - Kernel heap OOB write in PMRChangeSparseMemOSMem due to incorrect physical page translation from virtual page indexes
Summary
Software installed and run as a non-privileged user may conduct intentional GPU sparse memory API calls to cause out of bounds write in the kernel. The product incorrectly indexes internal state when performing sparse allocation remapping.
