VMware Patches Severe Security Flaws in Workstation and Fusion Products
Date: May 2024
CVE: CVE-2024-22267, CVE-2024-22268, CVE-2024-22269, CVE-2024-22270
Vulnerability Type: Use-After-Free, Heap Buffer Overflow, Information Disclosure
CWE: [[CWE-416]], [[CWE-122]], [[CWE-200]]
Sources: The Hacker News, Broadcom advisory
Issue Summary
Multiple severe security vulnerabilities have been identified in VMware Workstation and Fusion products. These vulnerabilities could potentially allow threat actors to execute arbitrary code, access sensitive information, and trigger denial-of-service (DoS) conditions. The affected versions include Workstation 17.x and Fusion 13.x.
Technical Key Findings
The vulnerabilities include a use-after-free issue in the Bluetooth device (CVE-2024-22267), a heap buffer overflow in the shader functionality (CVE-2024-22268), and two information disclosure flaws (CVE-2024-22269 and CVE-2024-22270). Exploiting these vulnerabilities requires local administrative privileges on a virtual machine, potentially allowing attackers to manipulate the VM's VMX process.
- CVE-2024-22267 (CVSS score: 9.3) - A use-after-free vulnerability in the Bluetooth device that could be exploited by a malicious actor with local administrative privileges on a virtual machine to execute code as the virtual machine's VMX process running on the host

Impact Assessment
Exploiting these vulnerabilities could lead to significant security breaches, including arbitrary code execution on the host machine, sensitive data exposure, and system crashes. The critical nature of these flaws underscores the need for immediate remediation to prevent potential attacks.
Patches or Workarounds
VMware has released patches for these vulnerabilities in versions 17.5.2 (Workstation) and 13.5.2 (Fusion). As temporary measures, users are advised to disable Bluetooth support and 3D acceleration features on virtual machines. However, there is no workaround for CVE-2024-22270.
