  - An information disclosure vulnerability exists in the
    Windows kernel that allows a local attacker, via a
    specially crafted application, to bypass the Address
    Space Layout Randomization (ASLR) feature and retrieve
    the memory address of a kernel object. (CVE-2016-7214)

  - Multiple elevation of privilege vulnerabilities exist in
    the Windows kernel-mode driver due to improper handling
    of objects in memory. A local attacker can exploit
    these, via a specially crafted application, to execute
    arbitrary code in kernel mode. (CVE-2016-7215,
    CVE-2016-7246, CVE-2016-7255)

  - An information disclosure vulnerability exists in the
    bowser.sys kernel-mode driver due to improper handling
    objects in memory. A local attacker can exploit this,
    via a specially crafted application, to disclose
    sensitive information. (CVE-2016-7218)");
