Just a week ago, we reported about a new jailbreak Unc0ver that would even work against the iOS 13.5. However, Apple was quick to address this matter. Now, they have released iOS 13.5.1 and other OS updates fixing the Unc0ver jailbreak vulnerability.

Apple iOS 13.5.1 Fixes Unc0ver Jailbreak Vulnerability

A week after the Unc0ver jailbreak surfaced online, Apple released iOS 13.5.1 addressing the vulnerability.

Wile Unc0ver boasted to successfully jailbreak all recent devices until iOS 13.5, it seems Apple has now halted its success.

Unc0ver jailbreak exploited a zero-day vulnerability in the operating system. Yet, with the recent update iOS 13.5.1 and iPadOS 13.5.1, Apple has clearly mentioned fixing the flaw. Describing the flaw CVE-2020-9859, Apple stated in its advisory,

 An application may be able to execute arbitrary code with kernel privileges.
A memory consumption issue was addressed with improved memory handling.

This update is available for all iPhones after iPhone 6s, iPad Air 2 and later, iPad mini 4 and later, and iPod touch 7th generation.

Bug Also Fixed In macOS, tvOS And watchOS

Unc0ver jailbreak successfully worked to jailbreak Mac, Apple Watch, and Apple TV as well.

However, Apple has also fixed the flaw for all these devices too, as it released tvOS 13.4.6, watchOS 6.2.6, and macOS Catalina 10.15.5 Supplemental Update, Security Update 2020-003 High Sierra.

Unc0ver’s lead developer pwn20wnd has also confirmed about the fix. Thus he advises the users not to install the latest OS updates if they want to jailbreak their devices.

Unc0ver’s website already warns the users about such updates.

unc0ver Team strongly cautions against installing any iOS software update that breaks unc0ver as you can’t re-jail​break on versions of iOS that are not supported by unc0ver at that time.

Moreover, with these updates, Apple has merely addressed the jailbreak flaw. For all the devices, they have released no other security technical bug fixes.

For instance, right after the launch of iOS 13.5, people complained about the battery drainage. But the updates address no such bugs.

Hence, for users who are looking forward to updating their devices for better performance, this update isn’t worth it. Whereas, those who want to get rid of the jailbreak vulnerability may update their devices to the latest OS versions.
