CVE-2021-26337
https://notcve.org/view.php?id=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. Una comprobación insuficiente de la dirección de la DRAM en System Management Unit (SMU) puede resultar en una lectura DMA desde una dirección de la DRAM no válida a la SRAM, resultando en que la SMU no atienda más peticiones • https://www.amd.com/en/corporate/product-security/bulletin/amd-sb-1027 •
