Today, Apple released its annual update across all its operating systems. With that, Apple not only released new features but also patched 261 different vulnerabilities. This is the most vulnerabilities Apple has ever patched, but the increase is not as significant as other vendors' "post-AI" patch releases.
In addition to the major "27" version, Apple also released bug-fix-only releases for the 26 branch of its operating systems and for 15 (Sequioa) for macOS. None of the vulnerabilities is labeled as being exploited. Apple does not note a severity to individual vulnerabilities.
There are some reports about difficulties downloading iOS 27. Users instead

Apple today released updates for iOS/iPadOS (26 and 18) and macOS 26. This update fixes 108 vulnerabilities and comes about two weeks after the much smaller macOS update that addressed the single screen-sharing vulnerability. This vulnerability did not affect iOS/iPadOS.
None of the vulnerabilities has been exploited so far. There are a few WebKit vulnerabilities, but no standalone Safari patch for older operating systems. 87 of the vulnerabilities affect only iOS 18, making this more of an iOS 18 release than one for the newer operating systems. Only six vulnerabilities affect all three OSs released today. All 6 vulnerabilities affect WebKit.
