Medium (4.7) in vmware. EPSS 0.5% chance of exploitation in the next 30 days.
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.

Additional conditions beyond the attacker's control need to be present for exploitation to be possible.
