Apple released emergency patches for multiple operating systems addressing CVE-2026-86950. The vulnerability affects iOS 26, macOS 26, and macOS 15, and is already being actively exploited in the wild. iOS and macOS 27 are not affected by this security issue. The current '27' branch update released today addresses only functional issues, not security concerns. A version 27.1 is also expected to support a new foldable iPhone device. The patches for older branches are the critical security fixes, while newer branch updates are routine maintenance. The active exploitation status makes this a high-priority patch for affected device users.
