What the flaw is

An input validation vulnerability exists in the VBoxDrv.sys driver of Sun xVM VirtualBox which allows attackers to locally execute arbitrary code.

CISA's description

The VBoxDrvNtDeviceControl function in VBoxDrv.sys in Sun xVM VirtualBox before 1.6.4 uses the METHOD_NEITHER communication method for IOCTLs and does not properly validate a buffer associated with the Irp object, which allows local users to gain privileges by opening the \\.\VBoxDrv device and calling DeviceIoControl to send a crafted kernel address.
