CVE-2026-28923

Sandbox escape via insufficient GPU log redaction

Published May 11, 2026 · Updated May 11, 2026

Sensitive-data logging in Apple macOS GPU Drivers before 14.8.7, 15.7.7, and 26.5 allows local users to escape an app sandbox. The GPU Drivers component logs data without sufficient redaction, but Apple has not disclosed the logged fields or the path that exposes them to a sandboxed app. A locally installed malicious app with low privileges is required; successful exploitation crosses the app container boundary, with no further impact disclosed.
