EPSS score
0.42%
Insufficient validation in parsing Owner's Certificate Authority (OCA) certificates in SEV (AMD Secure Encrypted Virtualization) and SEV-ES user application can lead to a host crash potentially resulting in denial of service.
7.8CVE-2021-26398amd1st gen epyc+66
EPSS score
0.21%
Insufficient input validation in SYS_KEY_DERIVE system call in a compromised user application or ABL may allow an attacker to corrupt ASP (AMD Secure Processor) OS memory which may lead to potential arbitrary code execution.
5.5CVE-2021-26354amd2nd gen amd epyc™ processors+169
EPSS score
0.18%
Insufficient bounds checking in ASP may allow an attacker to issue a system call from a compromised ABL which may cause arbitrary memory values to be initialized to zero, potentially leading to a loss of integrity.
5.5CVE-2021-26364amdepyc_7232p_firmware+44
EPSS score
0.22%
Insufficient bounds checking in an SMU mailbox register could allow an attacker to potentially read outside of the SRAM address range which could result in an exception handling leading to a potential denial of service.
9CVE-2021-26311amdepyc_7232p_firmware+65
EPSS score
1.68%
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.
7.8CVE-2021-26316amd1st gen epyc+152
EPSS score
0.26%
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.
7.4CVE-2021-26356amd1st gen amd epyc™ processors+105
EPSS score
0.40%
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.
5.5CVE-2021-26337amdathlon™ series+113
EPSS score
0.24%
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.
5.5CVE-2021-26388amdathlon™ series+108
EPSS score
0.22%
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.

EPSS score
0.16%
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.
4.9CVE-2021-26345amd2nd gen amd epyc™ processors+94
EPSS score
0.43%
