Apple Releases iOS 11.2.1 Update With HomeKit Remote Sharing Fix
The iOS 11.2.1 update can be downloaded for free on all eligible devices over-the-air in the Settings app. To access the update, go to Settings --> General --> Software Update.
The iOS 11.2.1 update addresses bugs and issues that have been discovered since the release of iOS 11.2.
According to Apple's release notes, the update re-enables remote access for shared users of the Home app. Apple broke remote access for shared users when implementing a fix for a major HomeKit vulnerability last week.
The HomeKit bug allowed unauthorized access to HomeKit accessories that included smart locks, and it was fixed server-side by Apple after it was made public. To address the issue immediately, Apple had to disable remote access for shared users, which the company said it would re-enable through an iOS update this week.
Following today's update, the HomeKit vulnerability is fully patched and remote access for shared users has been reinstated.
