5.5CVE-2021-26343amd3rd gen epyc+24
EPSS score
0.18%
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.
7.8CVE-2021-26398amd1st gen epyc+66
EPSS score
0.21%
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.
7.8CVE-2021-26316amd1st gen epyc+152
EPSS score
0.26%
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.
4.4CVE-2021-26396amd3rd gen epyc+24
EPSS score
0.11%
Insufficient validation of address mapping to IO in ASP (AMD Secure Processor) may result in a loss of memory integrity in the SNP guest.
4.4CVE-2021-26328amd3rd gen epyc+24
EPSS score
0.18%
Failure to verify the mode of CPU execution at the time of SNP_INIT may lead to a potential loss of memory integrity for SNP guests.
5.5CVE-2021-26355amd3rd gen epyc+24
EPSS score
0.17%
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.
7.1CVE-2021-26402amd2nd gen epyc+51
EPSS score
0.18%
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.
2.4CVE-2023-20528amd2nd gen epyc+51
EPSS score
0.24%
Insufficient input validation in the SMU may allow a physical attacker to exfiltrate SMU memory contents over the I2C bus potentially leading to a loss of confidentiality.
5.7CVE-2023-20523amd2nd gen epyc+51
EPSS score
0.18%
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.
7.5CVE-2023-20529amd2nd gen epyc+51
EPSS score
0.62%
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.
5.3CVE-2023-20532amd2nd gen epyc+51
EPSS score
0.56%
Insufficient input validation in the SMU may allow an attacker to improperly lock resources, potentially resulting in a denial of service.

EPSS score
0.60%
Improper syscall input validation in the ASP Bootloader may allow a privileged attacker to read memory out-of-bounds, potentially leading to a denial-of-service.
7.5CVE-2023-20531amd2nd gen epyc+51
EPSS score
0.62%
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.
6.5CVE-2023-20525amd2nd gen epyc+51
EPSS score
0.60%
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.
