CVE-2022-32793

Kernel-memory disclosure via GPU bounds-check failures

Published Aug 24, 2022 · Updated May 30, 2025

Out-of-bounds writes in Apple GPU Drivers in macOS before 12.5, tvOS before 15.6, and watchOS before 8.7 allow local users to read kernel memory. The drivers write beyond one or more undisclosed buffers because bounds checks do not adequately constrain app-supplied GPU input. Local app execution is required, and Apple reports kernel-memory disclosure without a corresponding integrity or availability impact.
