DATE CVE VULNERABILITY TITLE RISK
2023-01-11 CVE-2021-26316 Improper Input Validation vulnerability in AMD products
Failure to validate the communication buffer and communication service in the BIOS may allow an attacker to tamper with the buffer resulting in potential SMM (System Management Mode) arbitrary code execution.
local
low complexity
amd CWE-20
7.8
2023-01-11 CVE-2021-26398 Out-of-bounds Write vulnerability in AMD products
Insufficient input validation in SYS_KEY_DERIVE system call in a compromised user application or ABL may allow an attacker to corrupt ASP (AMD Secure Processor) OS memory which may lead to potential arbitrary code execution.
local
low complexity
amd CWE-787
7.8
2023-01-11 CVE-2021-26402 Out-of-bounds Write vulnerability in AMD products
Insufficient bounds checking in ASP (AMD Secure Processor) firmware while handling BIOS mailbox commands, may allow an attacker to write partially-controlled data out-of-bounds to SMM or SEV-ES regions which may lead to a potential loss of integrity and availability.
local
low complexity
amd CWE-787
7.1
2023-01-11 CVE-2023-20529 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in AMD products
Insufficient bound checks in the SMU may allow an attacker to update the from/to address space to an invalid value potentially resulting in a denial of service.
network
low complexity
amd CWE-119
7.5
2023-01-11 CVE-2023-20530 Improper Input Validation vulnerability in AMD products
Insufficient input validation of BIOS mailbox messages in SMU may result in out-of-bounds memory reads potentially resulting in a denial of service.
network
low complexity
amd CWE-20
7.5
2023-01-11 CVE-2023-20531 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in AMD products
Insufficient bound checks in the SMU may allow an attacker to update the SRAM from/to address space to an invalid value potentially resulting in a denial of service.

7.1
2022-05-10 CVE-2021-26353 Improper Initialization vulnerability in AMD products
Failure to validate inputs in SMM may allow an attacker to create a mishandled error leaving the DRTM UApp in a partially initialized state potentially resulting in loss of memory integrity.
local
low complexity
amd CWE-665
7.8
2022-05-10 CVE-2021-26370 Improper Input Validation vulnerability in AMD products
Improper validation of destination address in SVC_LOAD_FW_IMAGE_BY_INSTANCE and SVC_LOAD_BINARY_BY_ATTRIB in a malicious UApp or ABL may allow an attacker to overwrite arbitrary bootloader memory with SPI ROM contents resulting in a loss of integrity and availability.
local
low complexity
amd CWE-20
