Oracle VirtualBox crStateDeleteFramebuffersEXT Untrusted Pointer Dereference Privilege Escalation Vulnerability

This vulnerability allows local attackers to execute arbitrary code on vulnerable installations of Oracle VirtualBox. An attacker must first obtain the ability to execute low-privileged code on the target guest system in order to exploit this vulnerability. The specific flaw exists within the crStateDeleteFramebuffersEXT method. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the hypervisor.
