Apple has released iOS 26.5.2, a critical update that patches 25 security vulnerabilities in iPhones — and adds zero new features. The iOS 26.5.2 security update, released on June 29, 2026, fixes 25 security flaws affecting iPhone users worldwide. No new features are included, an unusual move that underscores Apple's focus on device protection. Apple regularly issues minor point updates for security, but a 25-patch release without any functional changes is rare. The update is available immediately for all compatible iPhones.
The 25 patches cover kernel-level exploits, WebKit flaws, and other system component vulnerabilities. While Apple has not released specific CVE details, such patches typically address memory corruption, privilege escalation, and remote code execution risks. This update applies to iPhone 17 and later models, including the iPhone 21 Pro. Security experts universally recommend installing the iOS 26.5.2 security update without delay. The lack of new features is a deliberate choice, prioritizing user safety over feature additions.
This update follows Apple's trend of proactive patching. Last year, iOS 26.4.1 fixed 18 vulnerabilities. The increase to 25 suggests a growing threat landscape. By releasing a security-only update, Apple signals that device integrity is paramount. Users risk exposure to exploits if they delay installation. The update is part of Apple's regular cycle, but the volume of patches makes this release more urgent.

The update is lightweight, around 200 MB, and takes minutes to install. Users can check Settings > General > Software Update.
