Apple only guarantees to fix all known issues and security bugs in their latest OS versions.

  Note: Because of dependency on architecture and system changes to any current version of Apple operating systems (for example, iOS 27, macOS 27, and so on), not all known security issues are addressed in previous versions (for example, iOS 26, macOS 26, and so on).
