CVE-2021-46763amd2nd gen amd epyc™+49
EPSS score0.49%
Insufficient input validation in the SMU may
enable a privileged attacker to write beyond the intended bounds of a shared
memory buffer potentially leading to a loss of integrity.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-2021-46762amd2nd gen amd epyc™+51EPSS score0.35%
Insufficient input validation in the SMU may
allow an attacker to corrupt SMU SRAM potentially leading to a loss of
integrity or denial of service.CVE-2021-46778amdamd processors+179EPSS score0.23%
Execution unit scheduler contention may lead to a side channel vulnerability found on AMD CPU microarchitectures codenamed “Zen 1”, “Zen 2” and “Zen 3” that use simultaneous multithreading (SMT). By measuring the contention level on scheduler queues an attacker may potentially leak sensitive information.CVE-2021-46769amd2nd gen amd epyc™+49EPSS score0.78%
Insufficient syscall input validation in the ASP
Bootloader may allow a privileged attacker to execute arbitrary DMA copies,
which can lead to code execution.CVE-2021-46764amd2nd gen amd epyc™+49EPSS score0.63%
Improper validation of DRAM addresses in SMU may
allow an attacker to overwrite sensitive memory locations within the ASP
potentially resulting in a denial of service.CVE-2020-12951amdathlon™ series+59EPSS 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-2022-29900amda10-9600p_firmware+214EPSS score3.94%
Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions.CVE-2022-27672amd1st gen amd epyc™ processors+274EPSS score0.28%
When SMT is enabled, certain AMD processors may speculatively execute instructions using a target
from the sibling thread after an SMT mode switch potentially resulting in information disclosure.CVE-2022-23823amda10-9600p_firmware+142EPSS score1.17%
A potential vulnerability in some AMD processors using frequency scaling may allow an authenticated attacker to execute a timing attack to potentially enable information disclosure.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-2022-23825amda10-9600p_firmware+255EPSS score0.78%
Aliases in the branch predictor may cause some AMD processors to predict the wrong branch type potentially leading to information disclosure.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.
