CVE-2025-43345

Sensitive data disclosure via undisclosed Kernel error

Published Nov 4, 2025 · Updated Nov 4, 2025

Kernel information disclosure in Apple iOS, iPadOS, macOS, tvOS, visionOS, and watchOS allows local users to read sensitive data. Apple identifies the Kernel as the affected component but has not disclosed the faulty operation or the checks missing from its data-access path. Exploitation requires a user to run an app locally; Apple has not bounded which sensitive data the app can read.
