Earlier in the month, Apple hurriedly released the iOS 11.2 to fix weird date glitch that made all iPhones, iPads and iPods suffer random reboots on December 2, but rushing the roll-out without proper checks has resulted in the company engineers overlooking a loophole in the new software that has now endangered the security of the customers at home.

Apparently, iOS 11.2 has security glitch that affects the HomeKit app that controls smart gadgets in the house including the door. With such serious flaw, anybody with knowledge of hacking can bypass the smart-lock of the door or garage-doors and enter the house.

Now, Apple iOS 11.2.1 weighs around 57MB in size (for iPhone 6) but will vary with different models and is said to be coming with the software patch to plug the aforementioned security loop-hole. All the eligible iPhone, iPads and iPods owners are urged to update their devices to the latest firmware as early as possible.
