CVE-2021-26407amd2nd gen epyc+1
EPSS score0.18%
A randomly generated Initialization Vector (IV) may lead to a collision of IVs with the same key potentially resulting in information disclosure.CVE-2021-26403amd1st gen epyc+42EPSS score0.12%
Insufficient checks in SEV may lead to a malicious hypervisor disclosing the launch secret potentially resulting in compromise of VM confidentiality.CVE-2021-26398amd1st gen epyc+66EPSS score0.21%
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.CVE-2021-26316amd1st gen epyc+152EPSS score0.26%
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.CVE-2021-26402amd2nd gen epyc+51EPSS score0.18%
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.CVE-2021-39298amd2nd gen epyc+191EPSS score0.37%
A potential vulnerability in AMD System Management Mode (SMM) interrupt handler may allow an attacker with high privileges to access the SMM resulting in arbitrary code execution which could be used by malicious actors to bypass security mechanisms provided in the UEFI firmware.CVE-2021-46768amd2nd gen epyc+3EPSS score0.17%
Insufficient input validation in SEV firmware may allow an attacker to perform out-of-bounds memory reads within the ASP boot loader, potentially leading to a denial of service.CVE-2021-46767amd2nd gen epyc+3EPSS score0.27%
Insufficient input validation in the ASP may allow an attacker with physical access, unauthorized write access to memory potentially leading to a loss of integrity or denial of service.CVE-2021-46779amd1st gen epyc+5EPSS score0.18%
Insufficient input validation in SVC_ECC_PRIMITIVE 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 loss of integrity and availability.CVE-2022-23813amd2nd gen epyc+3EPSS score0.50%
The software interfaces to ASP and SMU may not enforce the SNP memory security policy resulting in a potential loss of integrity of guest memory in a confidential compute environment.CVE-2023-20528amd2nd gen epyc+51EPSS score0.24%
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.CVE-2023-20523amd2nd gen epyc+51EPSS score0.18%
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.CVE-2023-20529amd2nd gen epyc+51EPSS score0.62%
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.CVE-2023-20532amd2nd gen epyc+51EPSS score0.56%
Insufficient input validation in the SMU may allow an attacker to improperly lock resources, potentially resulting in a denial of service.CVE-2023-20527amd1st gen epyc+66EPSS score0.60%
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.CVE-2023-20531amd2nd gen epyc+51EPSS score0.62%
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.CVE-2023-20522amd2nd gen epyc+3EPSS score0.62%
Insufficient input validation in ASP may allow an attacker with a malicious BIOS to potentially cause a denial of service.CVE-2023-20525amd2nd gen epyc+51EPSS score0.60%
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.
