Vulnerabilidades de AMD

Incorrect use of boot service in the AMD Platform Configuration Blob (APCB) SMM driver could allow a privileged attacker with local access (Ring 0) to achieve privilege escalation potentially resulting in arbitrary code execution.

Improper handling of direct memory writes in the input-output memory management unit could allow a malicious guest virtual machine (VM) to flood a host with writes, potentially causing a fatal machine check error resulting in denial of service.

A DLL hijacking vulnerability in Doc Nav could allow a local attacker to achieve privilege escalation, potentially resulting in arbitrary code execution.

Improper Access Control in an on-chip debug interface could allow a privileged attacker to enable a debug interface and potentially compromise data confidentiality or integrity.

Type confusion in the AMD Secure Processor (ASP) could allow an attacker to pass a malformed argument to the External Global Memory Interconnect Trusted Agent (XGMI TA) leading to a memory safety violation potentially resulting in loss of confidentiality, integrity, or availability.

An unintended proxy or intermediary in the AMD power management firmware (PMFW) could allow a privileged attacker to send malformed messages to the system management unit (SMU) potentially resulting in arbitrary code execution.

Incorrect permission assignment in AMD µProf may allow a local user-privileged attacker to achieve privilege escalation, potentially resulting in arbitrary code execution.

A DLL hijacking vulnerability in Vivado could allow a local attacker to achieve privilege escalation, potentially resulting in arbitrary code execution.

A DLL hijacking vulnerability in the AMD Software Installer could allow an attacker to achieve privilege escalation potentially resulting in arbitrary code execution.

Improper input validation in AMD Graphics Driver could allow an attacker to supply a specially crafted pointer, potentially leading to arbitrary code execution.

Integer Overflow within atihdwt6.sys can allow a local attacker to cause out of bound read/write potentially leading to loss of confidentiality, integrity and availability

A Time-of-check time-of-use (TOCTOU) race condition in the AMD Secure Processor (ASP) could allow an attacker to modify External Global Memory Interconnect Trusted Agent (XGMI TA) commands as they are processed potentially resulting in loss of confidentiality, integrity, or availability.

A Time-of-check time-of-use (TOCTOU) race condition in the AMD Secure Processor (ASP) could allow an attacker to corrupt memory resulting in loss of integrity, confidentiality, or availability.

Improper handling of parameters in the AMD Secure Processor (ASP) could allow a privileged attacker to pass an arbitrary memory value to functions in the trusted execution environment resulting in arbitrary code execution
