DescriptionCVE.org

A race condition was addressed with improved state handling. This issue is fixed in iOS 26.6 and iPadOS 26.6, macOS Tahoe 26.6, tvOS 26.6, watchOS 26.6. An app may be able to cause unexpected system termination.

AnalysisAI

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.
