DATE CVE VULNERABILITY TITLE RISK
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.

low complexity
amd CWE-119
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.

amd CWE-119
7.5
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
7.1
2021-12-10 CVE-2021-26340 Unspecified vulnerability in AMD products
A malicious hypervisor in conjunction with an unprivileged attacker process inside an SEV/SEV-ES guest VM may fail to flush the Translation Lookaside Buffer (TLB) resulting in unexpected behavior inside the virtual machine (VM).
