App crash via ImageIO texture integer overflow
Published Jul 27, 2026 · Updated Jul 27, 2026
Integer overflow in ImageIO in affected Apple operating systems allows attackers to crash an app by processing a maliciously crafted texture. Apple states that ImageIO inadequately validates texture input before an integer operation, but it has not disclosed the affected calculation or texture field. Exploitation requires a local context and user interaction that causes ImageIO to process the texture; Apple reports only unexpected app termination.
