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.
