DATE CVE VULNERABILITY TITLE RISK
2024-08-13 CVE-2023-20578 Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in AMD products
A TOCTOU (Time-Of-Check-Time-Of-Use) in SMM may allow an attacker with ring0 privileges and access to the BIOS menu or UEFI shell to modify the communications buffer potentially resulting in arbitrary code execution.
local
high complexity
amd CWE-367
6.4
2023-11-14 CVE-2021-46774 Unspecified vulnerability in AMD products
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.

7.5
2023-11-14 CVE-2023-20521 Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in AMD products
TOCTOU in the ASP Bootloader may allow an attacker with physical access to tamper with SPI ROM records after memory content verification, potentially leading to loss of confidentiality or a denial of service.
high complexity
amd CWE-367
5.7
2023-11-14 CVE-2023-20526 Unspecified vulnerability in AMD products
Insufficient input validation in the ASP Bootloader may enable a privileged attacker with physical access to expose the contents of ASP memory potentially leading to a loss of confidentiality.
low complexity
amd
4.6
2023-11-14 CVE-2023-20592 Unspecified vulnerability in AMD products
Improper or unexpected behavior of the INVD instruction in some AMD CPUs may allow an attacker with a malicious hypervisor to affect cache line write-back behavior of the CPU leading to a potential loss of guest virtual machine (VM) memory integrity.

6.5
2023-05-09 CVE-2021-26356 Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in AMD products
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.
network
high complexity
amd CWE-367
7.4
2023-05-09 CVE-2021-26371 Unspecified vulnerability in AMD products
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.
local
low complexity
amd
5.5
2023-01-11 CVE-2021-26398 Out-of-bounds Write vulnerability in AMD products
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.
local
low complexity
amd CWE-787
7.8
2023-01-11 CVE-2021-26403 Unspecified vulnerability in AMD products
Insufficient checks in SEV may lead to a malicious hypervisor disclosing the launch secret potentially resulting in compromise of VM confidentiality.
local
low complexity
amd
6.5
2023-01-11 CVE-2023-20527 Improper Input Validation vulnerability in AMD products
Improper syscall input validation in the ASP Bootloader may allow a privileged attacker to read memory out-of-bounds, potentially leading to a denial-of-service.
network
low complexity
amd CWE-20
