There’s an update for your Mac and iPhone to patch a serious zero-day vulnerability

On Monday, Apple released the latest round of updates to iOS and iPadOS (17.3), macOS (14.3), watchOS (10.3), and tvOS (17.3), which include a few new features, a smattering of bug fixes, and some pretty important security patches. Among them is a patch for a vulnerability that may have been exploited in the wild—in other words, you should rush to install the update and patch it.

The zero-day is the first Apple has fixed this year. It affects the following models: iPhone XS and later, iPad Pro 12.9-inch 2nd generation and later, iPad Pro 10.5-inch, iPad Pro 11-inch 1st generation and later, iPad Air 3rd generation and later, iPad 6th generation and later, and iPad mini 5th generation and later, as well as Macs running Sonoma, Ventura, and Monterey, and all Apple TV models. It was discovered as part of the WebKit Bugzilla program.

Apple also released a separate Safari update for macOS Ventura and Monterey that includes the fix, among other patches:
