Attack-Flow Graph

Executive Summary

This vulnerability is a race condition in Apple macOS versions prior to Sequoia 15.7.8, Sonoma 14.8.8, and Tahoe 26.6. A race condition occurs when a system's behavior depends on the sequence or timing of uncontrollable events, which can lead to unexpected results. In this case, the issue allows an app to potentially gain root privileges, which is the highest level of access on a system.

Impact Analysis

If exploited, this vulnerability could allow a malicious app to gain root privileges on your device. This means the app could execute commands with full system control, access sensitive data, install unauthorized software, or make system-wide changes without your consent. Users running unpatched macOS versions are at risk.

Mitigation Strategies

Update to the latest patched versions of macOS Sequoia 15.7.8, macOS Sonoma 14.8.8, or macOS Tahoe 26.6 to address the race condition and prevent potential root privilege escalation.
