Apple has just launched iOS 17.4, and right now everyone’s attention is focused on how it lets you run third-party app stores on your iPhone – although only if you're in the European Union. But there’s another important reason you should upgrade: it fixes two extremely serious security flaws.
In a new security post (via BleepingComputer), Apple says that iOS 17.4 and iPadOS 17.4 resolve two zero-day bugs in the iOS kernel and Apple’s RTKit that might allow an attacker to bypass your device’s kernel memory protections. That could potentially give malicious actors very high-level access to your device, so it’s imperative that you patch your iPhone as soon as possible by opening the Settings app, going to General > Software Update and following the on-screen instructions.
