Intel Corporation

Notified:  September 12, 2014 Updated: January 06, 2015

Status

  Not Affected

Vendor Statement

This vulnerability is caused by a misconfiguration of the platform by a platform-specific BIOS implementation. Intel has provided guidance to BIOS developers regarding write protection of the BIOS using System Management Mode (SMM) for many years. In preparation for the public disclosure of this issue, Intel has reiterated that guidance. This issue is mitigated by setting the SMM_BWP bit in the BIOS Control Register along with setting BIOS Lock Enable (BLE) and clearing BIOS Write Enable (BIOSWE). The SMM_BWP bit requires the processor to be in SMM in order to honor writes to the BIOS region of SPI flash, thereby mitigating the issue.
