CVE-2026-28943

Kernel-layout disclosure via insufficient log redaction

Published May 11, 2026 · Updated May 11, 2026

Information disclosure in IOHIDFamily across affected Apple operating systems allows local users to determine kernel memory layout. IOHIDFamily logs kernel-layout data without sufficient redaction, exposing address details to an app that can read the affected output. Local app execution is required; the result reveals layout information but does not directly expose kernel contents or modify the system.
