Local denial-of-service
Published Nov 4, 2025 · Updated Nov 4, 2025
Incorrect authorization in Apple macOS SoftwareUpdate allows local users to cause a denial-of-service through a locally installed app. Apple identifies a permissions error and states that vulnerable code was removed, but it has not disclosed the affected operation or how the app triggers the failure. Exploitation requires low local privileges and no user interaction; the documented consequence is limited to loss of availability.
