Oracle VirtualBox Insufficient Input Validation Vulnerability

KEVHIGH 8.8EPSS 6.93%

Does this matter?

Known to be exploited in the wild (CISA KEV, CISA remediation deadline 24 March 2022). Treat as an emergency change: patch or isolate now, then hunt for prior compromise.

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.
