IOS 11.2.1 rolls out with HomeKit fix

Posted December 15, 2017

The iOS 11.2.1 over-the-air update can be downloaded for free on all eligible devices by applying these simple steps.

According to security researchers, iOS 11.2 contains a security flaw that allows hackers to take control of the HomeKit app, which is used to operate smart gadgets in the home, including doors and security systems.

Last week the HomeKit app on the iOS devices was affected by a bug, which was responsible for giving unauthorised access to others, due to which users were exposed to unsafe circumstances. It's a serious threat to security, which is why Apple immediately issued a server side fix that didn't require an update. The latest minor software update restores remote access in HomeKit for shared users after Apple had disabled it earlier this month as a vulnerability fix. In order to try out the software you will need to be a registered developer. This update to iOS 11 is meant to address the HomeKit vulnerability. It's recommended to download the OTA update over Wi-Fi.

The new update is roughly 60MB to 70MB in size and also fixes an autofocus issue that some iPhone and iPad users reportedly faced after updating to iOS 11.2. With the new updates, for both platforms, Apple has promptly restored access for all users.

The Inquirer reported that Apple is already aware of the new issue brought by the iOS 11.2 update. On the Apple TV 4, although, you can install the update manually by downloading the IPSW file through iTunes. Apple iOS users who have not installed updates from the last few pushed out by the company might find the size of this current update to be slightly larger.
