Technical details

This vulnerability is a logic issue in Safari's state management mechanism, patched through improved state handling. The attack vector is network-based: an attacker can deliver maliciously crafted web content to trigger the vulnerability when a user visits a compromised or attacker-controlled website. No authentication or special user interaction beyond visiting a web page is required. Successful exploitation results in unexpected process termination (denial of service for the Safari process). The issue is fixed in Safari 27 and corresponding OS versions (iOS 27, iPadOS 27, macOS Golden Gate 27, tvOS 27, visionOS 27, watchOS 27), released on September 14, 2026.
