CVE-2025-31226

Denial of service via crafted image processing

Published May 12, 2025 · Updated Jul 25, 2026

Denial of service in Apple ImageIO on iOS, iPadOS, macOS, tvOS, visionOS, and watchOS allows attackers to interrupt apps via crafted images. Apple discloses only a logic issue addressed through improved checks; the exact ImageIO operation that mishandles the image is undisclosed. Image processing is required, and the bounded consequence is service interruption rather than disclosed data access or code execution.
