Local denial-of-service via Power Management type confusion
Published Sep 15, 2025 · Updated Sep 15, 2025
Type confusion in Power Management in Apple macOS before 26 allows local users to cause a denial-of-service through a locally running app. The component performs a memory operation on an object whose runtime type is incompatible with the type expected by the code. A locally running app is the required gate; Apple has not disclosed whether interruption manifests as a hang, crash, reboot, or shutdown.
