iOS 26.4.2
Definition
iOS 26.4.2 is a minor security and bug-fix update for Apple's iOS mobile operating system, released on April 22, 2026, primarily addressing vulnerabilities in Notification Services that could allow access to deleted push notification data.
This update patches flaws exploited to retain notification contents, such as in apps like Signal, and is available for iPhone 11 and later models.
As the second mid-release patch for iOS 26.4, it enhances privacy and stability without introducing major new features.
