Apple urges users to update to iOS 17.4 due to critical security flaw
Apple released iOS 17.4 on Tuesday, more than a month after the tech giant released iOS 17.3. While the latest update brings new emoji to all users and new app store capabilities to people in the European Union, it also patches a few issues that Apple said might be actively exploited.
To download the update, go to Settings > General > Software Update, tap Install Now and follow the onscreen prompts.
According to Apple, iOS 17.4 patches two security issues, which affect your iPhone's kernel and RTKit. The kernel is the software at the core of your operating system, while RTKit is Apple's real-time operating system. A real-time operating system is used when a large number of events must be accepted or processed in a certain amount of time, according to the computer science resource site Geeks for Geeks.
