A denial-of-service vulnerability in Apple ImageIO affects iOS, iPadOS, and macOS. When the vulnerable software processes a crafted image, insufficient validation or checking can cause the image-processing path to fail in a way that terminates the affected process or otherwise triggers a denial-of-service condition. Apple indicates the issue was addressed through improved checks. Fixed versions include iOS 26.6.1, iPadOS 26.6.1, and macOS Tahoe 26.6.2.
