CVE-2021-26402amd2nd gen epyc+51
EPSS 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.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.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.
