Kernel-state disclosure via improper authentication
Published Mar 25, 2026 · Updated Mar 25, 2026
Information disclosure in the Kernel across affected Apple operating systems allows local users to leak sensitive kernel state through an app. Apple states that the Kernel performs insufficient authentication, but has not disclosed the affected interface or the operation that exposes state. Execution of a local app is required; the documented consequence is limited to disclosure of sensitive kernel state, with no reported integrity or availability impact.
