Each row is the first time that source carried this signal. The analyst’s rows are its own findings.
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.
