CVE-2017-3197

GIGABYTE BRIX UEFI firmware fails to securely implement BIOS write protection

GIGABYTE BRIX UEFI firmware for the GB-BSi7H-6500 (version F6) and GB-BXi7-5775 (version F2) platforms does not securely implement BIOSWE, BLE, SMM_BWP, and PRx features. As a result, the BIOS is not protected from arbitrary write access and may permit modifications to the SPI flash.
