EDK2’s Network Package is vulnerable to a buffer overflow vulnerability due to the long server ID option in DHCPv6 clients. This vulnerability can be exploited by an attacker to gain unauthorized access and may result in a loss of confidentiality, integrity, and/or availability...
UEFI Shell module embedded in SPI Flash can be used to bypass Secure Boot
Overview The UEFI Shell program may expose raw memory access capabilities that, if present in platform firmware for debugging or advanced support use cases, could be abused to undermine UEFI Secure Boot protections. When the UEFI Shell is included in SPI flash, an attacker with the ability to...
From Silicon to Boot Code: Extending Automated Program Repair to Firmware-Layer Security Workarounds
Automated program repair APR research has been constrained to design time. Current techniques localize and fix bugs in RTL or HLS designs before a chip reaches production. Once a hardware vulnerability surfaces post-silicon, the patch must be manually generated: existing automation addresses patc...
