If you value up-to-date software security, you’ll want to update your Apple devices as soon as possible. According to a reputable source, Apple has released updates for iOS 15.3.1, iPadOS 15.3.1, macOS Monterey 12.2.1, and watchOS 8.4.2, all of which address a serious WebKit security vulnerability. A “use after free” flaw (that is, referencing memory after it has been freed for use) can be exploited by specially prepared websites to run arbitrary code on your device. This isn’t just a hypothetical exercise: Apple claims that the vulnerability was “actively exploited” before a patch was available.
The macOS update also addresses a battery drain issue with Intel-based MacBooks, however, the source claims that users of M1-based Macs have also experienced the issue. Meanwhile, the updated iOS version should resolve a problem with unresponsive Braille displays.
This is Apple’s third in-the-wild attack in 2022, following a kernel issue and a Safari problem that exposed your browser history and Google account information. While the updates aren’t particularly thrilling, they do indicate that Apple is committed to keeping up with potential attackers — and that there are more dangers to deal with in the first place.
