CVE-2020-12951amdathlon™ series+59
EPSS score0.22%
Race condition in ASP firmware could allow less privileged x86 code to perform ASP SMM (System Management Mode) operations.CVE-2020-12944amdathlon™ series+58EPSS score0.35%
Insufficient validation of BIOS image length by ASP Firmware could lead to arbitrary code execution.CVE-2020-12966amd1st/2nd/3rd gen amd epyc™ processors+107EPSS score0.31%
AMD EPYC™ Processors contain an information disclosure vulnerability in the Secure Encrypted Virtualization with Encrypted State (SEV-ES) and Secure Encrypted Virtualization with Secure Nested Paging (SEV-SNP). A local authenticated attacker could potentially exploit this vulnerability leading to leaking guest data by the malicious hypervisor.CVE-2020-12946amdathlon™ series+45EPSS score0.22%
Insufficient input validation in ASP firmware for discrete TPM commands could allow a potential loss of integrity and denial of service.CVE-2020-12954amd1st gen amd epyc™+60EPSS score0.23%
A side effect of an integrated chipset option may be able to be used by an attacker to bypass SPI ROM protections, allowing unauthorized SPI ROM modification.CVE-2020-12967amdepyc_7232p_firmware+65EPSS score1.68%
The lack of nested page table protection in the AMD SEV/SEV-ES feature could potentially lead to arbitrary code execution within the guest VM if a malicious administrator has access to compromise the server hypervisor.CVE-2020-12988amd1st/2nd/3rd gen amd epyc™ processors+61EPSS score1.04%
A potential denial of service (DoS) vulnerability exists in the integrated chipset that may allow a malicious attacker to hang the system when it is rebooted.CVE-2020-12961amd2nd gen amd epyc™+46EPSS score0.25%
A potential vulnerability exists in AMD Platform Security Processor (PSP) that may allow an attacker to zero any privileged register on the System Management Network which may lead to bypassing SPI ROM protections.CVE-2022-23824amda10-9600p_firmware+205EPSS score0.60%
IBPB may not prevent return branch predictions from being specified by pre-IBPB branch targets leading to a potential information disclosure.CVE-2022-23818amd3rd gen amd epyc™+23EPSS score0.50%
Insufficient input validation on the model
specific register: VM_HSAVE_PA may potentially lead to loss of SEV-SNP guest
memory integrity.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-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-2023-20528amd2nd 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-2023-20530amd3rd gen epyc+24EPSS score0.62%
Insufficient input validation of BIOS mailbox messages in SMU may result in out-of-bounds memory reads potentially resulting in a denial of service.CVE-2023-20584amdepyc_7203_firmware+66EPSS score0.19%
IOMMU improperly handles certain special address
ranges with invalid device table entries (DTEs), which may allow an attacker
with privileges and a compromised Hypervisor to
induce DTE faults to bypass RMP checks in SEV-SNP, potentially leading to a
loss of guest 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.
