Apple has released iOS 15.3 for iPhone and iPadOS 15.3 for iPad, both system software updates resolve the Safari 15 browser leak bug that generated some attention over a week ago, which allowed a nefarious site to extract a Google user ID along with website browsing data from a device.
The iOS/iPadOS 15.3 updates also include other security fixes, and perhaps a bug update or two, but the release notes are brief, simply stating that the updates are recommended for all users to install.
Additionally, Apple released macOS Monterey 12.2 update for Mac users to address the same Safari security bug, along with macOS Big Sur 11.6.3 and Security Update 2022-001 Catalina. Other system software updates are available for HomePod, watchOS 8.4, and tvOS 15.3 as well.
