Apple ships iOS 27.0 and iPadOS 27.0 (build 24A437); announcements list no security fixes

Apple released iOS 27.0 and iPadOS 27.0 (build 24A437) on 2026-09-14, following the iOS 27.0 RC on 2026-09-11; none of the announcements detail security fixes or CVEs.

Apple published the iOS 27.0 Release Candidate, build 24A437, on its developer release feed on 2026-09-11, then issued the general-availability versions of iOS 27.0 and iPadOS 27.0, both build 24A437, on 2026-09-14. All three notices link only to downloads and release notes and specify no vulnerability details, security fixes, or CVEs. Sources do not disagree on any facts. Because iOS major-version releases commonly bundle security fixes, security teams should review the full release notes for security content ahead of and after general availability.
