| Description | Software installed and run as a non-privileged user may conduct improper GPU system calls to pass invalid log2 page size when allocating physical pages leading to OOB read and/or write due to improper validation of the said value. Such crafted log2 page size could lead to 4K pages being treated as higher order pages and allowing read and/or write access to the memory beyond 4K threshold. | |
| Title | GPU DDK - Incorrect page size validation in PhysmemNewRamBackedPMR could lead to OOB read and/or write of arbitrary physical memory | |
