macOS vulnerability analysis and mitigation

CVE-2020-3904 is a security vulnerability discovered in Apple's macOS operating systems, specifically affecting the AppleGraphicsControl component. The vulnerability was disclosed and patched in March 2020 as part of macOS Catalina 10.15.4 security update. The issue affected multiple versions of macOS including High Sierra 10.13.6, Mojave 10.14.6, and Catalina 10.15.3 (Apple Support).

The vulnerability consists of multiple memory corruption issues in the AppleGraphicsControl component. These issues were addressed with improved state management in the system. The vulnerability could potentially allow malicious applications to execute arbitrary code with kernel privileges, representing a significant security risk to affected systems (Apple Support).

If exploited, this vulnerability would allow a malicious application to execute arbitrary code with kernel privileges. This level of access would give an attacker complete control over the affected system, potentially leading to full system compromise (Apple Support).

The vulnerability requires a malicious application to be present on the system to be exploited. The attack vector is local, requiring the attacker to have the ability to run code on the target system (Apple Support).

Apple addressed this vulnerability in macOS Catalina 10.15.4, Security Update 2020-002 Mojave, and Security Update 2020-002 High Sierra. Users should update their systems to these versions or later to protect against this vulnerability (Apple Support).
