Improper Access Control in the AMD SPI protection feature may allow a user with Ring0 (kernel mode) privileged access to bypass protections potentially resulting in loss of integrity and availability.

Certain size values in firmware binary headers could trigger out of bounds reads during signature validation, leading to denial of service or potentially limited leakage of information about out-of-bounds memory contents.

Improper access control in System Management Mode (SMM) may allow an attacker to write to SPI ROM potentially leading to arbitrary code execution.

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 leading to arbitrary code execution.

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 code execution in SMM.

Insufficient protections in System Management Mode (SMM) code may allow an attacker to potentially enable escalation of privilege via local access.

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 availability and integrity.

Failure to validate the AMD SMM communication buffer may allow an attacker to corrupt the SMRAM potentially leading to arbitrary code execution.

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.

Insufficient protections in System Management Mode (SMM) code may allow an attacker to potentially enable escalation of privilege via local access.

Improper input validation in the SMM Supervisor may allow an attacker with a compromised SMI handler to gain Ring0 access potentially leading to arbitrary code execution.
