CVE-2023-20569

A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address prediction. This may result in speculative execution at an attacker-controlled address, potentially leading to information disclosure.

CVE-2022-23821

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

CVE-2023-4969

A GPU kernel can read sensitive data from another GPU kernel (even from another user or app) through an optimized GPU memory region called local memory on various architectures.

CVE-2023-20579

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

CVE-2023-20571

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-2023-20563

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

CVE-2022-23820

Failure to validate the AMD SMM communication buffermay allow an attacker to corrupt the SMRAM potentially leading to arbitrarycode execution.

CVE-2023-20565

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

CVE-2021-46758

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.

CVE-2023-20596

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.

CVE-2023-20589

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.
