Vulnerability |
Description |
Impact |
---|---|---|
MASTERKEY |
Attacker who already has compromised the security of a system updates flash to corrupt its contents. AMD Secure Processor (PSP) checks do not detect the corruption. Requires administrative access to the targeted system. |
Circumvention of platform security controls. These changes are persistent following a system reboot. |
RYZENFALL |
Attacker who already has compromised the security of a system writes to AMD Secure Processor registers to exploit vulnerabilities in the interface between x86 and AMD Secure Processor (PSP). Requires administrative access to the targeted system. |
Circumvention of platform security controls. These changes are not persistent following a system reboot. Attacker may install difficult to detect malware in SMM (x86). |
FALLOUT |
Attacker who already has compromised the security of a system writes to AMD Secure Processor registers to exploit vulnerabilities in the interface between x86 and AMD Secure Processor (PSP). Requires administrative access to the targeted system. |
Circumvention of platform security controls. These changes are not persistent following a system reboot. Attacker may install difficult to detect malware in SMM (x86). |
CHIMERA |
Attacker who already has compromised the security of a system installs a malicious driver that exposes certain Promontory functions. Requires administrative access to the targeted system. |
Attacker accesses physical memory through the chipset. Attacker installs difficult to detect malware in the chipset but is not persistent across reboots. |
