DATE CVE VULNERABILITY TITLE RISK
2022-05-11 CVE-2021-26350 Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in AMD products
A TOCTOU race condition in SMU may allow for the caller to obtain and manipulate the address of a message port register which may result in a potential denial of service.
local
high complexity
amd CWE-367
4.7
2022-05-11 CVE-2021-26364 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in AMD products
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.
local
low complexity
amd CWE-119
5.5
2022-05-11 CVE-2021-26372 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in AMD products
Insufficient bound checks related to PCIE in the System Management Unit (SMU) may result in access to an invalid address space that could result in denial of service.
local
low complexity
amd CWE-119
5.5
2022-05-11 CVE-2021-26373 Improper Input Validation vulnerability in AMD products
Insufficient bound checks in the System Management Unit (SMU) may result in a system voltage malfunction that could result in denial of resources and/or possibly denial of service.

2022-05-11 CVE-2021-26378 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in AMD products
Insufficient bound checks in the System Management Unit (SMU) may result in access to an invalid address space that could result in denial of service.
local
low complexity
amd CWE-119
5.5
2022-05-11 CVE-2021-26388 Out-of-bounds Read vulnerability in AMD products
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.
local
low complexity
amd CWE-125
5.5
2022-05-11 CVE-2021-46744 Information Exposure Through Discrepancy vulnerability in AMD products
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.
local
low complexity
amd CWE-203
6.5
2022-05-10 CVE-2021-26370 Improper Input Validation vulnerability in AMD products
Improper validation of destination address in SVC_LOAD_FW_IMAGE_BY_INSTANCE and SVC_LOAD_BINARY_BY_ATTRIB in a malicious UApp or ABL may allow an attacker to overwrite arbitrary bootloader memory with SPI ROM contents resulting in a loss of integrity and availability.
local
low complexity
amd CWE-20
