VMware VMWare ESXi

Original NVD 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 15.5.5), and Fusion (11.x before 11.5.5) contain an out-of-bounds write vulnerability in the USB 3.0 controller (xHCI). A malicious actor with local administrative privileges on a virtual machine may be able to exploit this issue to crash the virtual machine's vmx process leading to a denial of service condition or execute code on the hypervisor from a virtual machine. Additional conditions beyond the attacker's control must be present for exploitation to be possible.
