According to foreign media reports, since August last year, users have disclosed to Apple a HomeKit application bug that exists on the iOS system, and hackers can directly attack iOS and PadOS products through this vulnerability and cause paralysis, and this vulnerability still exists in Apple ios 14 today. The vulnerability is as follows: If you change the HomeKit device name to a very long string, such as 500,000 strings in the test, the iOS and iPadOS devices that load the string will directly restart and brick directly. Since the name is stored in iCloud and syncs with all other iOS devices that are logged in to the same account, the bug may appear repeatedly on multiple devices under an Apple ID, feeling like a rush to the pot.
iOS 14 critical vulnerability doorlock
The vulnerability name is doorlock. At present, staying in iOS 14 and below versions, iOS 15 has limited the number of characters in the name, basically will not trigger bug startup from iOS 15 devices, but after experimentation, even if the device in your hand is iOS 15, as long as you have an iOS 14 device under the same AppleID and sync to iCloud, then no matter what the iOS version number is, it will directly change bricks. The current solution is that you can avoid iCloud syncing by disabling your home device in Control Center. At present, Apple officials have not responded. After all, the popularity of HomeKit in China is not high.
