Kernel-memory disclosure via Graphics Drivers out-of-bounds read
Published May 26, 2022 · Updated Oct 21, 2025
Out-of-bounds read in Graphics Drivers in Apple macOS allows local users to disclose kernel memory through malformed input. The component reads beyond an intended buffer because it inadequately validates attacker-controlled input; Apple has not disclosed the affected function or input format. Local access is required, and exploitation exposes kernel-memory contents without reported integrity or availability impact.
