System termination via GPU driver out-of-bounds read
Published Aug 29, 2025 · Updated Apr 2, 2026
An out-of-bounds read in Apple macOS GPU Drivers allows local users to cause unexpected system termination through a malicious app. The GPU Drivers component reads beyond an internal buffer boundary because bounds checks are insufficient; Apple has not disclosed the specific driver or input path. Exploitation requires local app execution, and the documented consequence is a system crash with no reported data disclosure or code execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <13.7.7
- Affected versionversion=0 <14.7.7
- Affected versionversion=0 <15.6
