BaseFortify

Publication date: 2025-07-15

Last updated on: 2025-07-15

Assigner: VMware

Description
VMware ESXi, Workstation, and Fusion contain an integer-underflow in VMCI (Virtual Machine Communication Interface) that leads to an out-of-bounds write. A malicious actor with local administrative privileges on a virtual machine may exploit this issue to execute code as the virtual machine's VMX process running on the host. On ESXi, the exploitation is contained within the VMX sandbox whereas, on Workstation and Fusion, this may lead to code execution on the machine where Workstation or Fusion is installed.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability is an integer-underflow in VMware's VMCI (Virtual Machine Communication Interface) that causes an out-of-bounds write. A malicious user with local administrative privileges on a virtual machine can exploit this flaw to execute code as the VMX process on the host. On ESXi, the exploit is limited to the VMX sandbox, but on Workstation and Fusion, it can lead to code execution on the host machine where these products are installed.


How can this vulnerability impact me? :

If exploited, this vulnerability allows an attacker with local admin access on a virtual machine to execute arbitrary code on the host system. This can lead to full compromise of the host system or the virtual machine's VMX process, potentially resulting in data loss, unauthorized access, or disruption of services.
