AnalysisAIv1 – Jul 28, 2026

A race condition in Apple operating systems (iOS, iPadOS, macOS, tvOS, watchOS) fixed in version 26.6 allows a local malicious app to cause unexpected system termination, resulting in a denial-of-service condition. No evidence of active exploitation or public exploit code exists, and EPSS indicates very low exploitation probability (0.16%). The NVD-assigned CVSS 9.8 appears inconsistent with the actual impact, which is limited to availability.

Attack Technique

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

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).
