CVE-2024-40818

Sensitive data disclosure via locked-device Siri options

Published Jul 29, 2024 · Updated Apr 2, 2026

Information disclosure in Siri in Apple iOS, iPadOS, macOS, and watchOS allows physically proximate attackers to access sensitive user data. Siri exposes options on a locked device without adequately enforcing the lock-state boundary; Apple has not disclosed which requests or data classes are exposed. Exploitation requires physical access to a locked device, and the reported consequence is limited to reading sensitive user data.
