To understand what makes this jailbreak possible, one must first understand the checkm8 exploit. Checkm8 is a permanent hardware vulnerability in Apple's BootROM—the very first code that executes when an iOS device starts up. Since BootROM code is stored in read-only hardware memory, Apple cannot patch this vulnerability through software updates; only a physical modification of the chipset could address it. This makes checkm8 an "unpatchable" exploit, meaning that any device affected by it can theoretically be jailbroken forever, regardless of which iOS version it runs.
