CVE-2021-26311amdepyc_7232p_firmware+65
EPSS score1.68%
In the AMD SEV/SEV-ES feature, memory can be rearranged in the guest address space that is not detected by the attestation mechanism which could be used by a malicious hypervisor to potentially lead to arbitrary code execution within the guest VM if a malicious administrator has access to compromise the server hypervisor.CVE-2021-26316amd1st gen epyc+152EPSS score0.26%
Failure to validate the communication buffer and communication service in the BIOS may allow an attacker to tamper with the buffer resulting in potential SMM (System Management Mode) arbitrary code execution.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-2021-26363amdathlon™ series+35EPSS score0.22%
A malicious or compromised UApp or ABL could potentially change the value that the ASP uses for its reserved DRAM, to one outside of the fenced area, potentially leading to data exposure.CVE-2021-26337amdathlon™ series+113EPSS score0.24%
Insufficient DRAM address validation in System Management Unit (SMU) may result in a DMA read from invalid DRAM address to SRAM resulting in SMU not servicing further requests.CVE-2021-26388amdathlon™ series+108EPSS score0.22%
Improper validation of the BIOS directory may allow for searches to read beyond the directory table copy in RAM, exposing out of bounds memory contents, resulting in a potential denial of service.CVE-2021-26333amdchipset_driver+1EPSS score0.52%
An information disclosure vulnerability exists in AMD Platform Security Processor (PSP) chipset driver. The discretionary access control list (DACL) may allow low privileged users to open a handle and send requests to the driver resulting in a potential data leak from uninitialized physical pages.CVE-2021-26352amdathlon™ series+31EPSS score0.22%
Insufficient bound checks in System Management Unit (SMU) PCIe Hot Plug table may result in access/updates from/to invalid address space that could result in denial of service.CVE-2021-26344amdamd athlon™ 3000 series desktop processors with radeon™ graphics+83EPSS score0.16%
An out of bounds memory write when processing the AMD
PSP1 Configuration Block (APCB) could allow an attacker with access the ability
to modify the BIOS image, and the ability to sign the resulting image, to
potentially modify the APCB block resulting in arbitrary code execution.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-2021-26353amd3rd gen epyc+23EPSS score0.27%
Failure to validate inputs in SMM may allow an attacker to create a mishandled error leaving the DRTM UApp in a partially initialized state potentially resulting in loss of memory integrity.CVE-2021-26408amd1st gen amd epyc™+39EPSS score0.27%
Insufficient validation of elliptic curve points in SEV-legacy firmware may compromise SEV-legacy guest migration potentially resulting in loss of guest's integrity or confidentiality.CVE-2021-26378amdathlon™ series+85EPSS score0.22%
Insufficient bound checks in the System Management Unit (SMU) may result in access to an invalid address space that could result in denial of service.CVE-2021-26318amdall supported processors+6EPSS score0.33%
A timing and power-based side channel attack leveraging the x86 PREFETCH instructions on some AMD CPUs could potentially result in leaked kernel address space information.CVE-2021-26396amd3rd gen epyc+24EPSS score0.11%
Insufficient validation of address mapping to IO in ASP (AMD Secure Processor) may result in a loss of memory integrity in the SNP guest.CVE-2021-26328amd3rd gen epyc+24EPSS score0.18%
Failure to verify the mode of CPU execution at the time of SNP_INIT may lead to a potential loss of memory integrity for SNP guests.CVE-2021-26335amdathlon™ series+59EPSS score0.29%
Improper input and range checking in the AMD Secure Processor (ASP) boot loader image header may allow an attacker to use attacker-controlled values prior to signature validation potentially resulting in arbitrary code execution.CVE-2021-26350amdepyc_7232p_firmware+44EPSS 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-2021-26366amdathlon_3050ge_firmware+64EPSS score0.24%
An attacker, who gained elevated privileges via some other vulnerability, may be able to read data from Boot ROM resulting in a loss of system integrity.
