Publication date: 2025-07-15

Last updated on: 2025-07-15

Assigner: VMware

Description
VMware ESXi, Workstation, and Fusion contain a heap-overflow vulnerability in the PVSCSI (Paravirtualized SCSI) controller 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 and exploitable only with configurations that are unsupported. 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 a heap-overflow issue in the PVSCSI (Paravirtualized SCSI) controller used by VMware ESXi, Workstation, and Fusion. It allows a malicious actor with local administrative privileges on a virtual machine to perform an out-of-bounds write, potentially enabling them to execute code as the VMX process on the host machine. On ESXi, exploitation is limited to unsupported configurations and contained within the VMX sandbox, while on Workstation and Fusion, it may lead to code execution on the host machine where these products are installed.


How can this vulnerability impact me? :

If exploited, this vulnerability can allow an attacker with local administrative access on a virtual machine to execute arbitrary code on the host system. This could lead to full compromise of the host machine running VMware Workstation or Fusion, or limited compromise within the VMX sandbox on ESXi under unsupported configurations. The impact includes potential loss of confidentiality, integrity, and availability of the host system and virtual machines.
