CVE-2026-34194
GPU DDK - UAF read and/or write to arbitrary physical pages in DevmemIntChangeSparse due to incorrect calculation of the virtual index count
Description
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.
