One week ago, a new version of the Unc0ver jailbreak was released, and it was working on the iOS 13.5 too!
Unfortunately, Apple quickly learned about the new version and addressed it. As a response, they have released iOS 13.5.1 and other updates to fix the vulnerability.
One week after the new jailbreak was posted online, Apple ate at its success by releasing iOS 13.5.1, which fixed the vulnerability that allowed the jailbreak to be installed.
The jailbreak used a zero-day vulnerability present in iOS. Apple has mentioned that they cleared that in both iOS 13.5.1 and iPadOS 13.5.1.
The flaw was labeled CVE-2020-9859, and this is what Apple stated about it:
“An application may be able to execute arbitrary code with kernel privileges. A memory consumption issue was addressed with improved memory handling.”
The new iOS update is available for all iOS devices after iPhone 6s, iPad Air 2, iPad mini 4, and iPod touch 7th gen.
The Unv0ver jailbreak was also functioning on Mac, Apple TV, and Apple Watch.
Apple has also patched the afferent vulnerabilities in tvOS 13.4.6, watchOS 6.2.6, and macOS Catalina 10.15.5.
The news was also confirmed by Unc0ver’s lead developer, pwn20wnd, in a tweet:
iOS 13.5.1 and tvOS 13.4.6 were just released to patch the kernel vulnerability used by the #unc0ver jailbreak. Do not update your devices.

Unc0ver’s official website advises fans and users not to update their devices since that would create problems:
“Unc0ver Team strongly cautions against installing any iOS software update that breaks unc0ver as you can’t re-jailbreak on versions of iOS that are not supported by unc0ver at that time.”
