CVE-2021-26406amd1st gen amd epyc™ processors+52
EPSS score0.42%
Insufficient validation in parsing Owner's
Certificate Authority (OCA) certificates in SEV (AMD Secure Encrypted Virtualization)
and SEV-ES user application can lead to a host crash potentially resulting in
denial of service.CVE-2021-26354amd2nd gen amd epyc™ processors+169EPSS score0.18%
Insufficient bounds checking in ASP may allow an
attacker to issue a system call from a compromised ABL which may cause
arbitrary memory values to be initialized to zero, potentially leading to a
loss of integrity.CVE-2021-26356amd1st gen amd epyc™ processors+105EPSS score0.40%
A TOCTOU in ASP bootloader may allow an attacker
to tamper with the SPI ROM following data read to memory potentially resulting
in S3 data corruption and information disclosure.CVE-2021-26345amd2nd gen amd epyc™ processors+94EPSS 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-2021-26371amd1st gen amd epyc™ processors+140EPSS score0.19%
A compromised or malicious ABL or UApp could
send a SHA256 system call to the bootloader, which may result in exposure of
ASP memory to userspace, potentially leading to information disclosure.CVE-2021-46756amd1st gen amd epyc™ processors+80EPSS score0.65%
Insufficient validation of inputs in
SVC_MAP_USER_STACK in the ASP (AMD Secure Processor) bootloader may allow an
attacker with a malicious Uapp or ABL to send malformed or invalid syscall to
the bootloader resulting in a potential denial of service and 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-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-2022-23829amd1st 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-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-2023-20592amd1st gen amd epyc™ processors+91EPSS score1.02%
Improper or unexpected behavior of the INVD instruction in some AMD CPUs may allow an attacker with a malicious hypervisor to affect cache line write-back behavior of the CPU leading to a potential loss of guest virtual machine (VM) 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-2023-20569amd1st gen amd epyc™ processors+338EPSS score7.30%
A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address prediction. This may result in speculative execution at an attacker-controlled address, potentially leading to information disclosure.CVE-2023-20526amd1st gen amd epyc™ processors+79EPSS score0.31%
Insufficient input validation in the ASP Bootloader may enable a privileged attacker with physical access to expose the contents of ASP memory potentially leading to a loss of confidentiality.CVE-2023-20593amd2nd gen amd epyc™ processors+259EPSS score5.19%
An issue in “Zen 2” CPUs, under specific microarchitectural circumstances, may allow an attacker to potentially access sensitive 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-2023-31315amd1st 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.
