Kernel-memory disclosure via insufficient AVEVideoEncoder redaction
Published Dec 12, 2023 · Updated Nov 4, 2025
Kernel-memory disclosure in Apple operating systems allows local users to expose sensitive kernel data through an AVEVideoEncoder app. AVEVideoEncoder insufficiently redacts sensitive information returned to the app, leaving kernel-memory contents exposed. Exploitation requires a local app and user interaction; the documented impact is read-only disclosure, with no integrity or availability effect.
