therefore, affected by multiple vulnerabilities :

  - Multiple elevation of privilege vulnerabilities exist in
    the kernel-mode driver due to improper handling of
    objects in memory. An authenticated, remote attacker can
    exploit these, via a specially crafted application, to
    run arbitrary code in kernel mode. (CVE-2016-3218,
    CVE-2016-3221)

  - An information disclosure vulnerability exists in the
    Windows Virtual PCI (VPCI) virtual service provider
    (VSP) due to improper handling of uninitialized memory.
    An authenticated, remote attacker can exploit this, via
    a specially crafted application, to disclose sensitive
    memory contents. (CVE-2016-3232)");
