CVE-2016-8222
What it is
A vulnerability has been identified in a signed kernel driver for the BIOS of some ThinkPad systems that can allow an attacker with Windows administrator-level privileges to call System Management Mode (SMM) services.

The setting or changing of BIOS passwords is not affected by this vulnerability.
