CVE-2019-8692

Vulnerability

The vulnerability resides in the AppleGraphicsControl component of macOS Mojave versions prior to 10.14.6. A validation issue exists that, when triggered, allows an application to read restricted memory. The issue is addressed with improved input sanitization in the fixed version [1].

Exploitation

An attacker requires the ability to run an application on the affected system. No special privileges or user interaction beyond launching the application are needed. The application can exploit the validation flaw to access memory that should be restricted, leading to information disclosure [1].

Impact

Successful exploitation enables an application to read restricted memory, potentially exposing sensitive data such as cryptographic keys, passwords, or other confidential information. The impact is limited to information disclosure; no code execution or privilege escalation is described [1].

Mitigation

Apple addressed this issue in macOS Mojave 10.14.6, released on July 22, 2019. Users should update to this version or later. No workarounds are documented for unpatched systems [1].
