Checkm8, by axi0mX (https://twitter.com/axi0mX/status/1177542201670168576), is a bootrom exploit for most modern iOS devices that was released earlier today, a little over 9 years since limera1n (https://www.theiphonewiki.com/wiki/Limera1n_Exploit)‘s release which was a bootrom exploit that worked on the iPhone 3GS/4 and other A4 devices. This exploit, which can be accessed from DFU mode, was patched by Apple in summer 2018 during the iOS 12 beta phase (https://twitter.com/axi0mX/status/1177544539046703104) and makes use of a UaF (use-after-free) vulnerability found in iBoot’s USB code.
Checkm8 works on Apple A5 to A11 (included) devices which include:
Every iPhone from the iPhone 4S to the iPhone 8 (Plus)/iPhone X
The iPod Touch 5, 6 and 7
Every iPad from the iPad 2 to the iPad 7th generation (no word has been given on whether the exploit is compatible with the iPad 7th generation (released in 2019) but it’s doubtful that Apple has released a bootROM update for A10 devices as the iPod Touch 7 was released earlier this year after the bug was found and patched and is still vulnerable to it (https://twitter.com/tie1r/status/1177621395859226625))
Every iPad Pro excluding the 2018 models
Every iPad Air excluding the iPad Air 3 (2019)
All iPad Mini devices excluding the iPad Mini 5 (2019)
