Apple releases high priority software update for iOS, iPadOS and macOS

THUNDER BAY – TECHNOLOGY – If you use an iPhone, iPad or Mac computer, this one is for you.

Apple has released a high priority security update for iOS 15.3.1, iPadOS 15.3.1 and macOS 12.2.1.

This upgrade will fix a critical zero-day vulnerability in Webkit that may have already been used in the wild.

Apple’s release notes describe the security content as follows:

  • 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: Processing maliciously crafted web content may lead to the execution of arbitrary code. Apple is aware of a report that this issue may have been actively exploited.
  • The description: A post-free usage issue has been addressed with better memory management.
  • CVE-2022-22620: an anonymous researcher

Webkit is Apple’s web rendering engine, and it should be used by all browsers on iOS, iPadOS, and macOS, not just Safari. This means that regardless of the browser you use on your iPhone, iPad or Mac, it is possible for users to create web content in a way that allows them to run whatever on your device. And worse, it may have already been used in the real world, rather than just discovered by security researchers.
