# CVE-2017-3197: GIGABYTE BRIX UEFI firmware fails to securely implement BIOS write protection

- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Published: 2018-07-09 · Updated: 2024-08-05

## Affected

- GIGABYTE GB-BSi7H-6500: F6
- GIGABYTE GB-BXi7-5775: F2

## 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.
