HIGH 7.1 ALL-YEARS

Published 2026-08-07 · Last modified 2026-08-07 · imaginationtech · NVD: Deferred

Software installed and run as a non-privileged user may conduct improper GPU system calls to cause OOB read kernel memory access and in certain cases cause GPU UAF of arbitrary pages. Incorrect validation of array index can lead to OOB read and potentially to GPU UAF of arbitrary pages.
