Legacy iPhones face unpatchable boot ROM flaw, prompting upgrade caution
Security researchers revealed a ROM-based vulnerability called usbliter8 in iPhones with A12/A13 chips (including XS/XS Max/XR, iPhone 11 family, and iPhone SE 2nd gen) and some iPads/Apple Watches. Because the flaw is in the boot ROM, it can’t be patched with software updates; exploitation requires physical access and can’t be triggered remotely, though user data remains protected. Affected devices will carry the vulnerability for their lifetime, so upgrading to newer hardware is the recommended mitigation when possible.
