An attacker with specialized hardware and physical access to an impacted device may be able to perform a voltage fault injection attack resulting in compromise of the ASP secure boot potentially…
• CVE-2023-20571, published 2023-11-14. High severity, CVSS 8.1. EPSS: 0.4% chance of exploitation in the next 30 days. A race condition in System Management Mode (SMM) code may allow an attacker using a compromised user space to leverage CVE-2018-8897 potentially resulting in privilege escalation.
• CVE-2021-46758, published 2023-11-14. Medium severity, CVSS 6.1. EPSS: 0.3% chance of exploitation in the next 30 days. Insufficient validation of SPI flash addresses in the ASP (AMD Secure Processor) bootloader may allow an attacker to read data in memory mapped beyond SPI flash resulting in a potential loss of…
• CVE-2023-20555, published 2023-08-08. High severity, CVSS 7.8. EPSS: 0.3% chance of exploitation in the next 30 days. Insufficient input validation in CpmDisplayFeatureSmm may allow an attacker to corrupt SMM memory by overwriting an arbitrary bit in an attacker-controlled pointer potentially leading to arbitrary…
• CVE-2023-20565, published 2023-11-14. High severity, CVSS 7.8. EPSS: 0.2% chance of exploitation in the next 30 days. Insufficient protections in System Management Mode (SMM) code may allow an attacker to potentially enable escalation of privilege via local access.
• CVE-2023-20563, published 2023-11-14. High severity, CVSS 7.8. EPSS: 0.2% chance of exploitation in the next 30 days. Insufficient protections in System Management Mode (SMM) code may allow an attacker to potentially enable escalation of privilege via local access.
