CVE-2024-40829

Lock-screen content disclosure via VoiceOver checks

Published Jul 29, 2024 · Updated Apr 2, 2026

Information disclosure in VoiceOver in affected Apple operating systems allows physically proximate attackers to view restricted lock-screen content. Apple has not published the precise VoiceOver check that mishandles requests for restricted content, disclosing only that improved checks resolved the issue. Physical access to a locked device is required, and the documented consequence is viewing restricted content without reported modification or service interruption.
