CVE-2021-26345amd2nd gen amd epyc™ processors+94
EPSS score0.43%
Failure to validate the value in APCB may allow a privileged attacker to tamper with the APCB token to force an out-of-bounds memory read potentially resulting in a denial of service.CVE-2021-46774amd1st gen amd epyc™ processors+149EPSS score0.51%
Insufficient DRAM address validation in System
Management Unit (SMU) may allow an attacker to read/write from/to an invalid
DRAM address, potentially resulting in denial-of-service.CVE-2022-23830amd3rd gen amd epyc™ processors+67EPSS score0.35%
SMM configuration may not be immutable, as intended, when SNP is enabled resulting in a potential limited loss of guest memory integrity.CVE-2022-23820amd3rd gen amd epyc™ processors+123EPSS score0.70%
Failure to validate the AMD SMM communication buffer
may allow an attacker to corrupt the SMRAM potentially leading to arbitrary
code execution.CVE-2022-23829amd1st gen amd epyc™ processors+23EPSS score0.20%
A potential weakness in AMD SPI protection features may allow a malicious attacker with Ring0 (kernel mode) access to bypass the native System Management Mode (SMM) ROM protections.CVE-2024-21978amd3rd gen amd epyc™ processors+89EPSS score0.49%
Improper input validation in SEV-SNP could allow a malicious hypervisor to read or overwrite guest memory potentially leading to data leakage or data corruption.CVE-2024-21980amd3rd gen amd epyc™ processors+89EPSS score0.45%
Improper restriction of write operations in SNP firmware could allow a malicious hypervisor to potentially overwrite a guest's memory or UMC seed resulting in loss of confidentiality and integrity.CVE-2023-20533amd2nd gen amd epyc™ processors+96EPSS score0.50%
Insufficient DRAM address validation in System
Management Unit (SMU) may allow an attacker to read/write from/to an invalid
DRAM address, potentially resulting in denial-of-service.CVE-2023-20566amd3rd gen amd epyc™ processors+68EPSS score0.37%
Improper address validation in ASP with SNP enabled may potentially allow an attacker to compromise guest memory integrity.CVE-2023-20521amd1st gen amd epyc™ processors+106EPSS score0.26%
TOCTOU in the ASP Bootloader may allow an attacker with physical access to tamper with SPI ROM records after memory content verification, potentially leading to loss of confidentiality or a denial of service.CVE-2023-31355amd3rd gen amd epyc™ processors+89EPSS score0.44%
Improper restriction of write operations in SNP firmware could allow a malicious hypervisor to overwrite a guest's UMC seed potentially allowing reading of memory from a decommissioned guest.CVE-2023-31315amd1st gen amd epyc™ processors+74EPSS score0.63%
Improper validation in a model specific register (MSR) could allow a malicious program with ring0 access to modify SMM configuration while SMI lock is enabled, potentially leading to arbitrary code execution.
