DATE CVE VULNERABILITY TITLE RISK
2023-05-09 CVE-2023-20520 Out-of-bounds Write vulnerability in AMD products
Improper access control settings in ASP Bootloader may allow an attacker to corrupt the return address causing a stack-based buffer overrun potentially leading to arbitrary code execution.
network
low complexity
amd CWE-787
critical
9.8
2023-05-09 CVE-2023-20524 Out-of-bounds Write vulnerability in AMD products
An attacker with a compromised ASP could possibly send malformed commands to an ASP on another CPU, resulting in an out of bounds write, potentially leading to a loss a loss of integrity.
network
low complexity
amd CWE-787
7.5
2023-03-01 CVE-2022-27672 Unspecified vulnerability in AMD products
When SMT is enabled, certain AMD processors may speculatively execute instructions using a target from the sibling thread after an SMT mode switch potentially resulting in information disclosure.
local
high complexity

4.7
2023-01-11 CVE-2021-26316 Improper Input Validation vulnerability in AMD products
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.
local
low complexity
amd CWE-20
7.8
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-2021-26402 Out-of-bounds Write vulnerability in AMD products
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.
local
low complexity
amd CWE-787
7.1
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

6.5
2023-01-11 CVE-2023-20523 Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in AMD products
TOCTOU in the ASP may allow a physical attacker to write beyond the buffer bounds, potentially leading to a loss of integrity or denial of service.
high complexity
amd CWE-367
5.7
2023-01-11 CVE-2023-20525 Improper Input Validation vulnerability in AMD products
Insufficient syscall input validation in the ASP Bootloader may allow a privileged attacker to read memory outside the bounds of a mapped register potentially leading to a denial of service.
network
low complexity
amd CWE-20
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
