Latest iOS update fixes a vulnerability used for jailbreaks

Apple has recently released iOS 13.5.1 to all supported iPhones, and while this is a surprising release that only seems to be adding minor improvements, it actually includes one very important change.

The Cupertino-based tech giant used this new software update for the iPhone to block the unc0ver jailbreak tool, essentially making it impossible to unlock the iPhone once again.

unc0ver is currently the most advanced jailbreak solution for the iPhone, as it supports all models out there even running iOS 13.5. unc0ver is also one of the jailbreak tools that have been extensively tested, and there’s no doubt many tried it out after the official launch a few weeks ago.

Goodbye, jailbreak!

But as it turns out, Apple wasn’t very happy with this new jailbreak solution, so the company released iOS 13.5.1 to block it. All devices that are updated to this new release would no longer be able to run the unc0ver jailbreak – Apple will soon block the downgrades to iOS 13.5 as well, essentially making the unlocking impossible unless the team working on unc0ver comes up with an update as well.

For the time being, however, Apple seems to have patched the vulnerability used for the jailbreak, so an update to unc0ver would technically require the team to come across another bug that would could be abused to unlock the device.

Apple says in the security release notes for iOS 13.5.1 that it included a kernel update that that resolves a memory consumption issue with improved memory handling. An application may be able to execute arbitrary code with kernel privileges, Apple says, and this is how unc0ver managed to jailbreak any iPhone 6s and later.

For the time being, there’s not much you can do if you want to stick with the jailbreak, other than not updating the iPhone to this new release.
