EPSS score0.23%
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.CVE-2021-26397amd3rd gen amd epyc™+23EPSS score0.18%
Insufficient address validation, may allow an
attacker with a compromised ABL and UApp to corrupt sensitive memory locations

Insufficient ID command validation in the SEV Firmware may allow a local authenticated attacker to perform a denial of service of the PSP.CVE-2021-26338amd2nd gen amd epyc™+45EPSS score0.93%
Improper access controls in System Management Unit (SMU) may allow for an attacker to override performance control tables located in DRAM resulting in a potential lack of system resources.CVE-2021-26330amd1st gen amd epyc™+60EPSS score0.22%
AMD System Management Unit (SMU) may experience a heap-based overflow which may result in a loss of resources.CVE-2021-26325amd3rd gen amd epyc™+20EPSS score0.22%
Insufficient input validation in the SNP_GUEST_REQUEST command may lead to a potential data abort error and a denial of service.CVE-2021-26322amd1st gen amd epyc™+59EPSS score1.05%
Persistent platform private key may not be protected with a random IV leading to a potential “two time pad attack”.CVE-2021-26332amd3rd gen amd epyc™+23EPSS score0.23%
Failure to verify SEV-ES TMR is not in MMIO space, SEV-ES FW could result in a potential loss of integrity or availability.CVE-2021-26320amd1st gen amd epyc™+59EPSS score0.19%
Insufficient validation of the AMD SEV Signing Key (ASK) in the SEND_START command in the SEV Firmware may allow a local authenticated attacker to perform a denial of service of the PSPCVE-2021-26323amd3rd gen amd epyc™+20EPSS score0.25%
Failure to validate SEV Commands while SNP is active may result in a potential impact to memory integrity.CVE-2021-26329amd1st gen amd epyc™+59EPSS score0.22%
