Apple Issues iOS 26.0.1 Patch for FontParser Flaw

Apple has released iOS 26.0.1 — a small, urgent bug‑fix and security update for iPhone and iPad users — and is urging people to install it. The update addresses recurring Wi‑Fi and Bluetooth disconnects on iPhone 17, iPhone 17 Pro and iPhone Air models, a limited number of cellular‑connectivity failures after iOS 26, camera artifacts in certain lighting, blank app icons when applying custom tints, and VoiceOver being disabled for some users. It includes a security fix for an out‑of‑bounds write in the FontParser framework (CVE‑2025‑43400) that could cause app termination or memory corruption if a malicious font is processed; Apple says it is withholding exploit details to give users time to patch. Apple also issued companion updates — macOS Tahoe 26.0.1 (which resolves an install failure on some Mac Studio M3 Ultra machines), iPadOS 26.0.1, watchOS 26.0.2, tvOS 26.0.1, visionOS 26.0.1 and iOS 18.7.1 for older devices. The releases add no new features and are available now via Settings > General > Software Update on supported devices.
