CVE-2025-43255

System termination via GPU driver out-of-bounds read

Published Aug 29, 2025 · Updated Apr 2, 2026

Out-of-bounds read in Apple macOS GPU Drivers allows local users to cause system termination through a malicious app. The driver reads beyond a buffer because bounds are not adequately validated, but Apple has not disclosed the affected routine or input. Execution of an app with low privileges on the Mac is required, and the documented consequence is a system crash without data impact.
