CVE-2020-3968: VMware Workstation xHCI Isoch TD Out-Of-Bounds Write Privilege Escalation Vulnerability

First published: Thu Jun 25 2020(Updated: )

This vulnerability allows local attackers to escalate privileges on affected installations of VMware Workstation. An attacker must first obtain the ability to execute high-privileged code on the target guest system in order to exploit this vulnerability. The specific flaw exists within the xHCI component. When parsing Isoch Transfer Descriptor (TD), the process does not properly validate user-supplied data that can result in a write past the end of an allocated object. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the hypervisor.
