CVE-2021-26332amd3rd gen amd epyc™+23
EPSS score0.23%
Failure to verify SEV-ES TMR is not in MMIO space, SEV-ES FW could result in a potential loss of integrity or availability.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-2021-26347amdepyc_7002_firmware+49EPSS score0.20%
Failure to validate the integer operand in ASP (AMD Secure Processor) bootloader may allow an attacker to introduce an integer overflow in the L2 directory table in SPI flash resulting in a potential denial of service.CVE-2021-26404amd3rd gen epyc+23EPSS score0.18%
Improper input validation and bounds checking in SEV firmware may leak scratch buffer bytes leading to potential information disclosure.CVE-2021-26372amdathlon™ series+46EPSS score0.22%
Insufficient bound checks related to PCIE in the System Management Unit (SMU) may result in access to an invalid address space that could result in denial of service.CVE-2021-46775amd2nd gen amd epyc™+49EPSS score0.32%
Improper input validation in ABL may enable an
attacker with physical access, to perform arbitrary memory overwrites,
potentially leading to a loss of integrity and code execution.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-2021-46771amd3rd gen amd epyc™+23EPSS score0.30%
Insufficient validation of addresses in AMD Secure Processor (ASP) firmware system call may potentially lead to arbitrary code execution by a compromised user application.CVE-2021-46763amd2nd gen amd epyc™+49EPSS 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-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-2023-20584amdepyc_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.
