CVE-2022-32858

Kernel-state disclosure via undisclosed memory handling

Published Nov 1, 2022 · Updated May 6, 2025

Information disclosure in Apple Neural Engine on macOS before 13 and watchOS before 9 allows local users to leak sensitive kernel state. Apple has not disclosed the affected routine or the memory-handling operation that exposes kernel state to an app. Execution of a local app with user interaction is required, and the reported consequence is limited to disclosure rather than modification or service interruption.
