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-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-2023-20555

Insufficient input validation inCpmDisplayFeatureSmm may allow an attacker to corrupt SMM memory by overwritingan arbitrary bit in an attacker-controlled pointer potentially leading toarbitrary code execution in SMM.

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.
