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.

Apple's vulnerability summary notes that the vulnerabilities patched in today's VisionOS release will be enumerated at a later date.

iOS 26.6.1 and iPadOS 26.6.1 iOS 18.7.10 and iPadOS 18.7.10 macOS Tahoe 26.6.2
