CVE-2020-2907: Oracle VirtualBox VBoxSVGA Type Confusion Privilege Escalation Vulnerability
This vulnerability allows local attackers to escalate privileges on affected installations of Oracle VirtualBox. 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 SVGA rendering command SVGA3DCMDDRAWPRIMITIVES. The issue results from the lack of proper validation of user-supplied data, which can result in a type confusion condition. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the hypervisor.
