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-2021-46766amd4th gen amd epyc™ processors+30EPSS score0.23%
Improper clearing of sensitive data in the ASP Bootloader may expose secret keys to a privileged attacker accessing ASP SRAM, potentially leading to a loss of confidentiality.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-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-2023-20566amd3rd 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-2023-20519amd3rd gen amd epyc™ processors+3EPSS score0.20%
A Use-After-Free vulnerability in the management of an SNP guest context page may allow a malicious hypervisor to masquerade as the guest's migration agent resulting in a potential loss of guest integrity.CVE-2023-20573amd3rd gen amd epyc™ processors+66EPSS score0.29%
A privileged attacker
can prevent delivery of debug exceptions to SEV-SNP guests potentially
resulting in guests not receiving expected debug information.CVE-2023-20575amd1st gen amd epyc™ processors+91EPSS score0.80%
A potential power side-channel vulnerability in some AMD processors may allow an authenticated attacker to use the power reporting functionality to monitor a program’s execution inside an AMD SEV VM potentially resulting in a leak of sensitive information.CVE-2023-20587amd1st gen amd epyc™ processors+7EPSS score0.17%
Improper
Access Control in System Management Mode (SMM) may allow an attacker access to
the SPI flash potentially leading to arbitrary code execution.CVE-2023-31347amd3rd gen amd epyc™ processors+64EPSS score0.46%
Due to a code bug in
Secure_TSC, SEV firmware may allow an attacker with high privileges to cause a
guest to observe an incorrect TSC when Secure TSC is enabled potentially
resulting in a loss of guest integrity.CVE-2023-31346amd3rd gen amd epyc™ processors+87EPSS score0.31%
Failure to initialize
memory in SEV Firmware may allow a privileged attacker to access stale data
from other guests.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.
