DATE CVE VULNERABILITY TITLE RISK
2022-05-12 CVE-2021-26351 Improper Input Validation vulnerability in AMD products
Insufficient DRAM address validation in System Management Unit (SMU) may result in a DMA (Direct Memory Access) read/write from/to invalid DRAM address that could result in denial of service.

low complexity
amd CWE-20
5.5
2022-05-12 CVE-2021-26361 Unspecified vulnerability in AMD products
A malicious or compromised User Application (UApp) or AGESA Boot Loader (ABL) could be used by an attacker to exfiltrate arbitrary memory from the ASP stage 2 bootloader potentially leading to information disclosure.

5.5
2022-05-12 CVE-2021-26362 Unspecified vulnerability in AMD products
A malicious or compromised UApp or ABL may be used by an attacker to issue a malformed system call which results in mapping sensitive System Management Network (SMN) registers leading to a loss of integrity and availability.
local
low complexity
amd
7.1
2022-05-12 CVE-2021-26366 Unspecified vulnerability in AMD products
An attacker, who gained elevated privileges via some other vulnerability, may be able to read data from Boot ROM resulting in a loss of system integrity.

7.1
2022-05-12 CVE-2021-26369 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in AMD products
A malicious or compromised UApp or ABL may be used by an attacker to send a malformed system call to the bootloader, resulting in out-of-bounds memory accesses.
local
low complexity
amd CWE-119
7.8
2022-05-11 CVE-2021-26339 Unspecified vulnerability in AMD products
A bug in AMD CPU’s core logic may allow for an attacker, using specific code from an unprivileged VM, to trigger a CPU core hang resulting in a potential denial of service.
local
low complexity
amd
5.5
2022-05-11 CVE-2021-26342 Unspecified vulnerability in AMD products
In SEV guest VMs, the CPU may fail to flush the Translation Lookaside Buffer (TLB) following a particular sequence of operations that includes creation of a new virtual machine control block (VMCB).

3.3
2022-05-11 CVE-2021-26347 Improper Validation of Specified Quantity in Input vulnerability in AMD products
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.
local
high complexity
amd CWE-1284
4.7
2022-05-11 CVE-2021-26348 Unspecified vulnerability in AMD products
Failure to flush the Translation Lookaside Buffer (TLB) of the I/O memory management unit (IOMMU) may lead an IO device to write to memory it should not be able to access, resulting in a potential loss of integrity.
local
low complexity
amd
5.5
2022-05-11 CVE-2021-26349 Unspecified vulnerability in AMD products
Failure to assign a new report ID to an imported guest may potentially result in an SEV-SNP guest VM being tricked into trusting a dishonest Migration Agent (MA).
