VMware Workstation (14.x before 14.1.1, 12.x) and Fusion (10.x before 10.1.1 and 8.x) contain a denial-of-service vulnerability which can be triggered by opening a large number of VNC sessions. Note: In order for exploitation to be possible on Workstation and Fusion, VNC must be manually enabled.

Security readout for executives and security teams

This vulnerability can make affected VMware Workstation or Fusion installations unavailable when VNC is manually enabled and many VNC sessions are opened. It is not described as data theft or code execution. Business urgency is highest where older desktop virtualization hosts expose VNC for remote VM access. Exposure is likely limited to legacy VMware Workstation or Fusion systems where VNC was manually enabled. Default installations without VNC enabled are not indicated as exploitable in the provided description. Treat this as a targeted availability risk for legacy virtualization endpoints, not a broad enterprise compromise issue. Prioritize remediation where VNC is enabled or where affected systems support critical development, operations, or security workflows. Mitigation focus: Update Workstation 14.x to 14.1.1 or later where applicable.; Update Fusion 10.x to 10.1.1 or later where applicable.; Disable VNC on Workstation or Fusion unless it is operationally required..
