Apple released the iOS 12.4.1 update on Monday, which according to the update notes consists of “important security and stability updates”. This update comes a little more than a month after the iOS 12.4 update that brought wireless data transfer from one iPhone to another, among other features.
According to the release notes, the 12.4.1 update fixes a kernel issue (CVE-2019-8605) that potentially allowed a “malicious application to execute arbitrary code with system privileges”. The vulnerability, which was discovered by Ned Williamson working with Google Project Zero, allowed jailbreak of iPhones updated with iOS 12.4.
The iOS 12.4.1 update is 70.3MB in size and like any other iOS 12 update, it’s available to iPhone 5s and later, iPad Air and later, and 6th-gen iPod touch.
To update, it’s recommended that you backup your data before updating, then go to the Settings app, head over to General, tap on Software Update on the next window and once your supported device is done searching for the update, you’ll find Download and Install at the bottom of the display. Tap on it and your iOS device will start updating to iOS 12.4.1. Also, remember to charge your device completely before updating or update while charging the device to ensure that the update doesn’t get hindered.
