Vulnerabilidades do AMD AMD Ryzen™ Embedded 8000 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.

Use of uninitialized resource within the AMD Platform Management Framework (PMF) could allow an attacker to read a uninitialized kernel memory resulting in loss of confidentiality or availability.

A buffer overflow vulnerability within AMD Sensor Fusion Hub Driver can allow a local attacker to write out of bounds, potentially resulting in denial of service or crash

An out of bounds read within the AMD Platform Management Framework (PMF) could allow an attacker to trigger a read of an arbitrary memory location potentially resulting in loss of availability or confidentiality.

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.

Improper access control between the Joint Test Action Group (JTAG) and Advanced Extensible Interface (AXI) could allow an attacker with physical access to read or overwrite the contents of cross-chip debug (XCD) registers potentially resulting in loss of data integrity or confidentiality.

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 could allow a local attacker to trigger a Use-After-Free (UAF) condition, potentially resulting in a loss of platform integrity or crash.

An improper input validation vulnerability within the AMD Platform Management Framework (PMF) driver can allow a local attacker to read Out-of-Bounds potentially resulting in information disclosure or a crash

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 enforcement of the LFENCE serialization property may allow an attacker to bypass speculation barriers and potentially disclose sensitive information, potentially resulting in loss of confidentiality.

Improper restriction of operations within the bounds of a memory buffer in PCIe® Link could allow an attacker with access to a guest virtual machine to potentially perform a denial of service attack against the host resulting in loss of availability.

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.
