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.

EPSS score
0.27%
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.
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.

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.
4.7CVE-2021-26347amdepyc_7002_firmware+49
EPSS score
0.20%
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.
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.
5.6CVE-2021-46778amdamd processors+179
EPSS score
0.23%
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.
7CVE-2020-12951amdathlon™ series+59
EPSS score
0.22%
