CVE-2017-3197
As a result, the BIOS is not protected from arbitrary write access and may permit modifications to the SPI flash.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.57%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
