When the name of a HomeKit device is changed to a large string (500,000 characters in testing), any device with an affected iOS version installed that loads the string will be disrupted, even after rebooting. Restoring a device and signing back into the iCloud account linked to the HomeKit device will again trigger the bug. There are two main scenarios that may occur afterwards, as outlined in the "Effects" section of this document.
