Vulnerabilidades do AMD AMD Ryzen™ AI 300 Series Processors

Improper input validation in the System Management Mode (SMM) communications buffer could allow a privileged attacker to perform an out of bounds read or write to a limited section of the Top of Memory Segment (TSEG) memory region, potentially resulting in loss of confidentiality or integrity.

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.

An out-of-bounds read in power management firmware by a malicious local attacker with low privileges could potentially lead to a partial loss of confidentiality and availability.

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 input validation in the AMD OverDrive (AOD) System Management Mode (SMM) module could allow a privileged attacker to perform an out-of-bounds read, potentially resulting in loss of confidentiality.

Improper privilege management in the KVM key download component could allow an attacker to swap tokens and download sensitive keys, potentially resulting in unauthorized access to privileged resources and loss of confidentiality.

Missing authentication in the KVM key download endpoint could allow an unauthenticated attacker with knowledge of the exposed URL to retrieve sensitive keys, potentially leading to loss of confidentiality.

Debug code left active in AMD's Video Decoder Engine Firmware (VCN FW) could allow a attacker to submit a maliciously crafted command causing the VCN FW to perform read/writes HW registers, potentially impacting confidentiality, integrity and availabilability of the system.

Improper input validation in AMD Graphics Driver could allow a local attacker to write out of bounds, potentially resulting in loss of integrity 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.

Improper input validation in the SMM communications buffer could allow a privileged attacker to perform an out of bounds read or write to SMRAM potentially resulting in loss of confidentiality or integrity.
