Attack-Flow Graph

Executive Summary

This is a race condition vulnerability where a sandboxed app could potentially exploit improper state management to gain kernel-level privileges. It was fixed in multiple Apple OS versions including iOS, iPadOS, macOS, tvOS, visionOS, and watchOS.

Detection Guidance

This vulnerability is specific to Apple operating systems and requires checking the installed version against the patched releases. For iOS/iPadOS, macOS, tvOS, visionOS, and watchOS, verify if the system version is below the fixed release (e.g., iOS 26.7 or later). No direct commands are provided in the context to detect this vulnerability.

Impact Analysis

A malicious app could execute arbitrary code with full kernel privileges, potentially allowing unauthorized access to system resources, data theft, or complete device compromise if the app is installed on your device.

Compliance Impact

The vulnerability allows a sandboxed app to execute arbitrary code with kernel privileges, which could lead to unauthorized access to sensitive data. This may impact compliance with GDPR (data protection) and HIPAA (health information privacy) by increasing the risk of data breaches or unauthorized data exposure.

Mitigation Strategies

Update affected Apple devices to the latest patched versions immediately: iOS 26.7 or 27, iPadOS 26.7 or 27, macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7, tvOS 27, visionOS 27, or watchOS 27. Ensure automatic updates are enabled to prevent future vulnerabilities.
