Technical Description
VMware ESXi (7.0 before ESXi_7.0.0-1.20.16321839, 6.7 before ESXi670-202006401-SG and 6.5 before ESXi650-202005401-SG), Workstation (15.x before 15.5.2), and Fusion (11.x before 11.5.2) contain an information leak in the EHCI USB controller. A malicious actor with local access to a virtual machine may be able to read privileged information contained in the hypervisor's memory. Additional conditions beyond the attacker's control need to be present for exploitation to be possible.
Remediation
Check the references section for vendor advisories and patches from vmware. Update cloud_foundation to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
