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-2021-26346 Integer Overflow or Wraparound vulnerability in AMD products
Failure to validate the integer operand in ASP (AMD Secure Processor) bootloader may allow an attacker to introduce an integer overflow in the L2 directory table in SPI flash resulting in a potential denial of service.
local
low complexity
amd CWE-190
5.5
2023-01-11 CVE-2021-26355 Resource Exhaustion 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.
local
low complexity
amd CWE-400
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 Improper Input Validation 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-20
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-2021-26403 Unspecified vulnerability in AMD products
