CVE-2023-31315 [HIGH] CWE-94 CVE-2023-31315: Improper validation in a model specific register (MSR) could allow a malicious program with ring0 ac Improper validation in a model specific register (MSR) could allow a malicious program with ring0 access to modify SMM configuration while SMI lock is enabled, potentially leading to arbitrary code execution.

CVE-2021-46757 [HIGH] CWE-119 CVE-2021-46757: Insufficient checking of memory buffer in ASP Secure OS may allow an attacker with a malicious TA to Insufficient checking of memory buffer in ASP Secure OS may allow an attacker with a malicious TA to read/write to the ASP Secure OS kernel virtual address space potentially leading to privilege escalation.

CVE-2023-20579 [MEDIUM] CWE-284 CVE-2023-20579: Improper Access Control in the AMD SPI protection feature may allow a user with Ring0 (kernel mode) 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.

CVE-2022-23821 [CRITICAL] CVE-2022-23821: Improper access control in System Management Mode (SMM) may allow an attacker to write to SPI ROM po Improper access control in System Management Mode (SMM) may allow an attacker to write to SPI ROM potentially leading to arbitrary code execution.

CVE-2021-46754 [CRITICAL] CWE-20 CVE-2021-46754: Insufficient input validation in the ASP (AMD Secure Processor) bootloader may allow an attacker wit Insufficient input validation in the ASP (AMD Secure Processor) bootloader may allow an attacker with a compromised Uapp or ABL to coerce the bootloader into exposing sensitive information to the SMU (System Management Unit) resulting in a potential loss of confidentiality and integrity.

CVE-2020-12930 [HIGH] CVE-2020-12930: Improper parameters handling in AMD Secure Processor (ASP) drivers may allow a privileged attacker t Improper parameters handling in AMD Secure Processor (ASP) drivers may allow a privileged attacker to elevate their privileges potentially leading to loss of integrity.

CVE-2021-26392 [HIGH] CWE-787 CVE-2021-26392: Insufficient verification of missing size check in 'LoadModule' may lead to an out-of-bounds write p Insufficient verification of missing size check in 'LoadModule' may lead to an out-of-bounds write potentially allowing an attacker with privileges to gain code execution of the OS/kernel by loading a malicious TA.

CVE-2021-26393 [MEDIUM] CWE-401 CVE-2021-26393: Insufficient memory cleanup in the AMD Secure Processor (ASP) Trusted Execution Environment (TEE) ma Insufficient memory cleanup in the AMD Secure Processor (ASP) Trusted Execution Environment (TEE) may allow an authenticated attacker with privileges to generate a valid signed TA and potentially poison the contents of the process memory with attacker controlled data resulting in a loss of confidentiality.
