Kernel memory disclosure to local applications
Published May 11, 2026 · Updated May 11, 2026
Kernel information disclosure in iOS, iPadOS, macOS, tvOS, visionOS, and watchOS allows local users to read kernel memory through an app. Apple identifies the Kernel component and says inadequate memory handling exposes kernel contents, but has not published the flawed operation or input path. Execution of an app on the device is required; the documented consequence is disclosure only, with no reported kernel write or service interruption.

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 <18.7.9
- Affected versionversion=0 <26.5
