Sensitive information leak via validation logic
Published Sep 8, 2021 · Updated Aug 3, 2024
Information disclosure in Apple iOS and iPadOS before 14.5 allows local users to leak sensitive user information via a malicious application. A validation issue in a CoreFoundation-related system component applies incorrect logic when processing application-controlled data, permitting disclosure from protected process or system state. Exploitation requires a malicious application installed on the device; the documented impact is information leakage without reported integrity or availability effects.
