Apple today released patches for all of its operating systems. However, only patches for older branches include a security fix. The vulnerability being addressed in iOS 26, macOS 26 and macOS 15 is already being exploited. iOS and macOS 27 are not affected. Today's update for the current "27" branch does not address security issues, but fixes some functional issues that got caught after the release two weeks ago. A 27.1 version was also expected to support the new foldable iPhone and will likely include specific features geared to the soon to be available device.

Apple credits Meta Product Security with reporting the vulnerability and states that: "Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals on versions of iOS before iOS 27".
