Vulnerabilidades do AMD AMD Ryzen™ Z2 Series Processors Extreme

Insecure default configuration state of DDR5 memory module by AGESA Bootloader Firmware could allow an attacker with local user privilege to abuse the unprotected PMIC interface to create a permanent denial of service condition or affect the integrity of the memory module.

A System Management Mode (SMM) handler could perform a callout to code located in non-SMM/untrusted memory. A highly privileged attacker could, with active user interaction and under high complexity and present preconditions, trigger execution of attacker-controlled code in SMM, potentially compromising the system’s confidentiality, integrity, and availability.

Improper Input validation in the AMD Secure Processor (ASP) PCI driver may allow a local attacker to create a buffer overflow condition, potentially resulting in a crash or denial of service

Improper isolation of shared resources on a system on a chip by a malicious local attacker with high privileges could potentially lead to a partial loss of integrity.
