CVE-2021-26401

LFENCE/JMP (mitigation V2-2) may not sufficiently mitigate CVE-2017-5715 on some AMD CPUs.

CVE-2023-20593

An issue in “Zen 2” CPUs, under specific microarchitectural circumstances, may allow an attacker to potentially access sensitive information.

CVE-2021-26351

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.

CVE-2021-26352

Insufficient bound checks in System Management Unit (SMU) PCIe Hot Plug table may result in access/updates from/to invalid address space that could result in denial of service.

CVE-2021-26346

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.

CVE-2021-26354

Insufficient bounds checking in ASP may allow anattacker to issue a system call from a compromised ABL which may causearbitrary memory values to be initialized to zero, potentially leading to aloss of integrity.

CVE-2021-26336

Insufficient bounds checking in System Management Unit (SMU) may cause invalid memory accesses/updates that could result in SMU hang and subsequent failure to service any further requests from other components.

CVE-2021-26371

A compromised or malicious ABL or UApp couldsend a SHA256 system call to the bootloader, which may result in exposure ofASP memory to userspace, potentially leading to information disclosure.

CVE-2021-46778

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 inform...

CVE-2021-26337

Insufficient DRAM address validation in System Management Unit (SMU) may result in a DMA read from invalid DRAM address to SRAM resulting in SMU not servicing further requests.
