CVE-2024-27880

App termination via ImageIO out-of-bounds read

Published Sep 16, 2024 · Updated Apr 2, 2026

Out-of-bounds read in Apple ImageIO across iOS, iPadOS, macOS, tvOS, visionOS, and watchOS allows attackers to terminate apps. ImageIO inadequately validates file input before reading from a buffer, causing an out-of-bounds read during file processing. Exploitation requires a user or app to process a malicious file; the documented consequence is app termination, with no reported code execution or data exposure.
