A race condition was identified in Apple operating systems that allows an application to read sensitive user data before proper validation. The issue was fixed with additional validation logic in the OS. The vulnerability could enable a malicious or compromised app to access personal information without the user’s intent or permission, constituting a confidentiality breach and possible integrity impact.

The bug affects Apple iOS, iPadOS, macOS (Sequoia 15.7.x, Sonoma 14.x, Tahoe 26.x), tvOS, visionOS, and watchOS across all versions released prior to the fixed updates. The patch is available in iOS 26.5, iPadOS 26.5, macOS Sequoia 15.7.7, macOS Sonoma 14.8.7, macOS Tahoe 26.5, tvOS 26.5, visionOS 26.5, and watchOS 26.5.

The EPSS score is not available and the vulnerability is not listed in the CISA KEV catalog, indicating an unknown exploitation probability. Based on the description, the most likely attack vector is a malicious or compromised application that can trigger the race condition while accessing private data. Without a public exploit or detailed scoring, defenders should treat the risk as significant, especially in environments where applications have broad data access.
