A couple of weeks back Apple released iOS 13.5 and with it came its joint contact tracing API with Google. Now it has released its latest 13.5.1 update which addresses some security issues.

iOS 13.5.1, along with iPadOS 13.5.1, addresses a security vulnerability linked to the Unc0ver jailbreak. This jailbreak was released shortly after iOS 13.5 dropped in May and allowed users to jailbreak even the most recent Apple devices such as the iPhone SE and 2020 iPad Pro.

9To5Mac have theorised that the new update patches the oday kernel vulnerability being utilised by Unc0ver.This patch has also been confirmed on Apple’s security website.

It states:

Kernel: Available for: iPhone 6s and later, iPad Air 2 and later, iPad mini 4 and later, and iPod touch 7th generation Impact: An application may be able to execute arbitrary code with kernel privileges Description: A memory consumption issue was addressed with improved memory handling.

Other updates available from today include watchOS 6.2.6 and some updates to Apple TV and HomePod.

The security update comes just a few weeks after Apples big iOS 13.5 update that introduced the company’s Exposure Notification System API that it developed in collaboration with Google. It has yet to be implemented with Australia’s contact tracing app, COVIDSafe.
