Apple has surprisingly released iOS 13.5.1 and iPadOS 13.5.1 published and in doing so closed a loophole that allowed a jailbreak on all iPhone or iPad devices running the operating system.
The latest iOS 13.5.1 update appears to be for the current jailbreak, which can be performed using the unc0ver tool. Apple's security website states that iOS 13.5.1 fixes a vulnerability in the system that allowed applications to "execute arbitrary code with kernel privileges." At the same time, the company noted that this is the same vulnerability discovered by the unc0ver team. Accordingly, devices running iOS 13.5.1 can no longer be jailbroken. Apple's Description is it [called:
kernel
Available for: iPhone 6s and later, iPad Air 2 and later, iPad mini 4 and later, and iPod touch 7.
Impact: An application may be able to execute arbitrary code with kernel privileges
Description: A memory consumption issue was fixed with improved memory handling.
CVE-2020-9859: un0ver
The difference between unc0ver and checkkm8
The jailbreak tool from unc0ver uses a so-called zero-day kernel exploit that was discovered shortly after the last release of iOS 13.5. This has enabled users to crack any iPhone or iPad device (including the latest generation) running iOS 13.5. While the jailbreak tool checkkm8 is based on a hardware vulnerability and can therefore crack all iPhone models from the iPhone 4S to the iPhone X, the unc0ver tool requires a kernel exploit - a software-based vulnerability that can also be used to crack new devices. iOS 13.5 is currently still being signed and can therefore be reinstalled after an update to iOS 13.5.1. However, it can be assumed that Apple will stop signing iOS 13.5 soon. (Photo by kentoh / Bigstockphoto)
