CVE-2021-26371amd1st gen amd epyc™ processors+140
EPSS 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-2021-26340amdamd 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-2021-26323amd3rd gen amd epyc™+20EPSS score0.25%
Failure to validate SEV Commands while SNP is active may result in a potential impact to memory integrity.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 score0.19%
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-2021-26355amd3rd gen epyc+24EPSS score0.18%
Insufficient fencing and checks in System Management Unit (SMU) may result in access to invalid message port registers that could result in a potential 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-2021-46775amd2nd 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-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.
