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.
