System termination via GPU driver out-of-bounds read
Published May 26, 2026 · Updated May 26, 2026
An out-of-bounds read in Apple macOS GPU Drivers before 26 allows local users to terminate the system through a malicious app. The drivers read beyond a buffer boundary because the affected path lacks adequate bounds checking; Apple has not disclosed the specific routine or input structure. Exploitation requires locally running an app, and the documented consequence is system termination without reported data disclosure or modification.
