Description

VMware ESXi (7.0 before ESXi_7.0.0-1.20.16321839, 6.7 before ESXi670-202004101-SG and 6.5 before ESXi650-202005401-SG), Workstation (15.x before 15.5.2), and Fusion (11.x before 11.5.2) contain a heap-overflow due to a race condition issue in the USB 2.0 controller (EHCI). A malicious actor with local access to a virtual machine may be able to exploit this vulnerability to execute code on the hypervisor from a virtual machine. Additional conditions beyond the attacker's control must be present for exploitation to be possible.
