local
low complexity
amd CWE-665
4.4
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-2021-26328 Unspecified vulnerability in AMD products

4.4
2023-01-11 CVE-2021-26343 Exposure of Resource to Wrong Sphere vulnerability in AMD products
Insufficient validation in ASP BIOS and DRTM commands may allow malicious supervisor x86 software to disclose the contents of sensitive memory which may result in information disclosure.
local
low complexity
amd CWE-668
5.5
2023-01-11 CVE-2021-26355 Unspecified vulnerability in AMD products
Insufficient fencing and checks in System Management Unit (SMU) may result in access to invalid message port registers that could result in a potential denial-of-service.

5.5
2023-01-11 CVE-2021-26396 Insufficient Verification of Data Authenticity vulnerability in AMD products
Insufficient validation of address mapping to IO in ASP (AMD Secure Processor) may result in a loss of memory integrity in the SNP guest.
local
low complexity
amd CWE-345
4.4
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-2023-20523 Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in AMD products
TOCTOU in the ASP may allow a physical attacker to write beyond the buffer bounds, potentially leading to a loss of integrity or denial of service.
high complexity
amd CWE-367
5.7
2023-01-11 CVE-2023-20525 Improper Input Validation vulnerability in AMD products
Insufficient syscall input validation in the ASP Bootloader may allow a privileged attacker to read memory outside the bounds of a mapped register potentially leading to a denial of service.
network
low complexity
amd CWE-20
