checkm8 is a use-after-free, not a heap overflow

2020-06-10T15:15:48Z

Added that checkm8 also supports Haywire and Homepod

2020-05-27T18:36:05Z

Fixed URL title in the references section.

2020-05-27T18:35:15Z

Replaced "Touch Bar" with "bridgeOS" and added a reference for it.

 The '''checkm8 exploit''' is a [[bootrom]] exploit with a CVE ID of CVE-2019-8900 used to run unsigned code on iOS, iPadOS, tvOS, watchOS, bridgeOS, audioOS, and Haywire devices with processors between an A5 and an A11, a S1P and a S3, a S5L8747, and a T2 (and thereby [[jailbreak]] it). Jailbreaks based on checkm8 are [[semi-tethered jailbreak]]s as the exploit works by taking advantage of a use-after-free in the USB DFU stack.
