Apple introduced new patches for iPhone, iPad, and Mac that can save you from being hacked. The releases were iOS 14.7.1 and iPadOS 14.7.1 and macOS Big Sur 11.5.1. With the release of the macOS Big Sur just last week, updates are already available because of how vulnerable your device is without the patches.
These patches released by Apple are said to address the exploitation of CVE-2021-30807 by applications, to perform unpredictable access to kernel privileges on an unpatched device. Access to kernel privileges can give hackers complete control over your device.
Apple said there was information that the zero-day vulnerability has been exploited but refrained from commenting more on the subject.
As per Apple’s brief:
- Available for: iPhone 6s and later, iPad Pro (all models), iPad Air 2 and later, iPad 5th generation 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. Apple is aware of a report that this issue may have been actively exploited.
- Description: A memory corruption issue was addressed with improved memory handling.
- CVE-2021-30807: an anonymous researcher
According to MacRumors:
The iOS and iPadOS 14.7 updates also address a number of other security vulnerabilities related to audio files, Find My, PDFs, web images, and more so all iPhone and iPad users should update to the new iOS 14.7 updates as soon as possible.
