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-2021-26376

Insufficient checks in System Management Unit (SMU) FeatureConfig may result in reenabling features potentially resulting in denial of resources and/or denial of service.

CVE-2021-26388

Improper validation of the BIOS directory may allow for searches to read beyond the directory table copy in RAM, exposing out of bounds memory contents, resulting in a potential denial of service.

CVE-2021-26375

Insufficient General Purpose IO (GPIO) bounds check in System Management Unit (SMU) may result in access/updates from/to invalid address space that could result in denial of service.

CVE-2021-26382

An attacker with root account privileges can load any legitimately signed firmware image into the Audio Co-Processor (ACP,) irrespective of the respective signing key being declared as usable for authenticating an ACP firmware image, potentially resulting in a denial of service.

CVE-2021-26378

Insufficient bound checks in the System Management Unit (SMU) may result in access to an invalid address space that could result in denial of service.

CVE-2021-26373

Insufficient bound checks in the System Management Unit (SMU) may result in a system voltage malfunction that could result in denial of resources and/or possibly denial of service.

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-2021-26384

A malformed SMI (System Management Interface) command may allow an attacker to establish a corrupted SMI Trigger Info data structure, potentially leading to out-of-bounds memory reads and writes when triggering an SMI resulting in a potential loss of resources.

CVE-2023-20558

Insufficient control flow management in AmdCpmOemSmm may allow a privileged attacker to tamper with the SMM handler potentially leading to an escalation of privileges.

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.

CVE-2021-26367

A malicious attacker in x86 can misconfigure the Trusted Memory Regions (TMRs), which may allow the attacker to set an arbitrary address range for the TMR, potentially leading to a loss of integrity and availability.

CVE-2021-26365

Certain size values in firmware binary headerscould trigger out of bounds reads during signature validation, leading todenial of service or potentially limited leakage of information aboutout-of-bounds memory contents.

CVE-2023-20559

Insufficient control flow management in AmdCpmGpioInitSmm may allow a privileged attacker to tamper with the SMM handler potentially leading to escalation of privileges.
