CVE-2021-26350amdepyc_7232p_firmware+44
EPSS score0.14%
A TOCTOU race condition in SMU may allow for the caller to obtain and manipulate the address of a message port register which may result in a potential denial of service.CVE-2021-26321amd1st gen amd epyc™+59EPSS score0.25%
Insufficient ID command validation in the SEV Firmware may allow a local authenticated attacker to perform a denial of service of the PSP.CVE-2021-26373amdathlon™ series+89EPSS score0.22%
Insufficient bound checks in the System Management Unit (SMU) may result in a system voltage malfunction that could result in denial of resources and/or possibly denial of service.CVE-2021-26338amd2nd gen amd epyc™+45EPSS score0.93%
Improper access controls in System Management Unit (SMU) may allow for an attacker to override performance control tables located in DRAM resulting in a potential lack of system resources.CVE-2021-26312amdathlon™ series+59EPSS score0.25%
Failure to flush the Translation Lookaside Buffer (TLB) of the I/O memory management unit (IOMMU) may lead an IO device to write to memory it should not be able to access, resulting in a potential loss of integrity.CVE-2021-26330amd1st gen amd epyc™+60EPSS score0.22%
AMD System Management Unit (SMU) may experience a heap-based overflow which may result in a loss of resources.CVE-2021-26375amdathlon™ series+85EPSS score0.22%
Insufficient General Purpose IO (GPIO) bounds check in System Management Unit (SMU) may result in access/updates from/to invalid address space that could result in denial of service.CVE-2021-26341amda10-9600p_firmware+125EPSS score0.32%
Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result in data leakage.CVE-2021-26322amd1st gen amd epyc™+59EPSS score1.05%
Persistent platform private key may not be protected with a random IV leading to a potential “two time pad attack”.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-2021-26401amda10-9600p_firmware+216EPSS score0.29%
LFENCE/JMP (mitigation V2-2) may not sufficiently mitigate CVE-2017-5715 on some AMD CPUs.CVE-2021-26340amdamd epyc™+105EPSS score0.25%
A malicious hypervisor in conjunction with an unprivileged attacker process inside an SEV/SEV-ES guest VM may fail to flush the Translation Lookaside Buffer (TLB) resulting in unexpected behavior inside the virtual machine (VM).CVE-2021-26320amd1st gen amd epyc™+59EPSS score0.19%
Insufficient validation of the AMD SEV Signing Key (ASK) in the SEND_START command in the SEV Firmware may allow a local authenticated attacker to perform a denial of service of the PSPCVE-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-2021-26372amdathlon™ 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-2021-26402amd2nd gen epyc+51EPSS score0.18%
Insufficient bounds checking in ASP (AMD Secure Processor) firmware while handling BIOS mailbox commands, may allow an attacker to write partially-controlled data out-of-bounds to SMM or SEV-ES regions which may lead to a potential loss of integrity and availability.CVE-2021-26329amd1st gen amd epyc™+59EPSS score0.22%
AMD System Management Unit (SMU) may experience an integer overflow when an invalid length is provided which may result in a potential loss of resources.CVE-2021-46744amdamd processors+99EPSS score0.33%
An attacker with access to a malicious hypervisor may be able to infer data values used in a SEV guest on AMD CPUs by monitoring ciphertext values over time.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.
