EPSS score
0.29%
AMD System Management Unit (SMU) contains a potential issue where a malicious user may be able to manipulate mailbox entries leading to arbitrary code execution.
7.8CVE-2021-26315amd3rd gen amd epyc™+20
EPSS score
0.17%
When the AMD Platform Security Processor (PSP) boot rom loads, authenticates, and subsequently decrypts an encrypted FW, due to insufficient verification of the integrity of decrypted image, arbitrary code may be executed in the PSP when encrypted firmware images are used.
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.
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.
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.
4.4CVE-2021-26396amd3rd gen epyc+24
EPSS score
0.11%
Insufficient validation of address mapping to IO in ASP (AMD Secure Processor) may result in a loss of memory integrity in the SNP guest.
4.4CVE-2021-26328amd3rd gen epyc+24
EPSS score
0.18%
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.
7.8CVE-2021-26335amdathlon™ series+59
EPSS score
0.29%
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.
5.5CVE-2021-26330amd1st gen amd epyc™+60
EPSS score
0.22%
AMD System Management Unit (SMU) may experience a heap-based overflow which may result in a loss of resources.
5.5CVE-2021-26371amd1st gen amd epyc™ processors+140
EPSS score
0.19%
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.
5.5CVE-2021-26404amd3rd gen epyc+23
EPSS score
0.18%
Improper input validation and bounds checking in SEV firmware may leak scratch buffer bytes leading to potential information disclosure.
5.5CVE-2021-26355amd3rd gen epyc+24
EPSS score
0.17%
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.
7.1CVE-2021-26402amd2nd gen epyc+51
EPSS score
0.18%
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.
6.5CVE-2021-46744amdamd processors+99
EPSS score
0.33%
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.
