CVE-2018-6972: VMware ESXi vulnerability

CVE-2018-6972: VMware ESXi (6.7 before ESXi670-201806401-BG, 6.5 before ESXi650-201806401-BG, 6.0 before ESXi600-201806401...

VMware ESXi (6.7 before ESXi670-201806401-BG, 6.5 before ESXi650-201806401-BG, 6.0 before ESXi600-201806401-BG and 5.5 before ESXi550-201806401-BG), Workstation (14.x before 14.1.2), and Fusion (10.x before 10.1.2) contain a denial-of-service vulnerability due to NULL pointer dereference issue in RPC handler. Successful exploitation of this issue may allow attackers with normal user privileges to crash their VMs.

Security readout for executives and security teams

This VMware issue can let a normal VM user crash their own virtual machine. The known impact is availability disruption, not data theft or host takeover. It matters most where affected ESXi, Workstation, or Fusion versions support business-critical or shared user workloads. Exposure is limited to environments still running the listed older VMware ESXi, Workstation, or Fusion releases. Risk is higher in multi-user labs, VDI, development, or hosting environments where normal users can interact with VMs. Treat as a targeted availability risk for legacy VMware estates. It is not described as host compromise, but VM crashes can disrupt operations where virtualization supports critical services or shared users. Mitigation focus: Upgrade ESXi to the applicable fixed 201806401-BG build or later.; Upgrade Workstation 14.x to 14.1.2 or later.; Upgrade Fusion 10.x to 10.1.2 or later..
