Overview

• The update is available now for iPhone 11 and later and is billed as an important stability and security release.
• Fixes address Wi‑Fi and Bluetooth disconnects on iPhone 17 and iPhone Air models, photo artifacts under certain lighting, cellular connection failures for a subset of users, blank app icons after Home Screen tinting, and a VoiceOver issue.
• The security content closes CVE-2025-43400 in FontParser, where a malicious font could cause memory corruption or unexpected app termination.
• Apple also shipped iOS 18.7.1 with the same security fix for devices not on iOS 26, including iPhone XS, XS Max, and XR users who cannot upgrade to the new cycle.
• Early reports note improved performance and battery life for many, though some users still see CarPlay drops and specific cellular problems as Apple tests iOS 26.1 for further fixes.
