CVE-2024-27835

Lock-screen note disclosure via improper state management

Published May 13, 2024 · Updated Apr 2, 2026

Information disclosure in Notes in Apple iOS and iPadOS before 17.5 allows physically proximate attackers to read notes from the lock screen. Notes state management permits stored content to remain accessible while the device is locked; Apple has not disclosed the specific faulty transition or check. Exploitation requires physical access to a supported iPhone or iPad and exposes note contents without reported modification or broader device control.
