AnalysisAIv1 – Sep 15, 2026

A race condition in core Apple operating system components lets a locally installed app trigger an unexpected system termination on iOS, iPadOS, macOS, tvOS, visionOS and watchOS. Apple fixed the flaw through improved state handling in iOS 26.7/27, iPadOS 26.7/27, macOS Sequoia 15.8, macOS Tahoe 26.7, macOS Golden Gate 27, tvOS 27, visionOS 27 and watchOS 27. Impact is availability-only (no data exposure or modification), exploitation requires a local malicious app and winning a timing window, EPSS is a low 0.21%, and no public exploit code or active exploitation has been identified at time of analysis.

Attack Technique

Information Disclosure MEDIUM

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.

Race Condition MEDIUM

Race conditions occur when multiple concurrent requests exploit the brief time gap between checking a condition and acting upon it (TOCTOU - Time of Check, Time of Use).
