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 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.

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

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

The integer overflow vulnerability within AMD Graphics driver could allow an attacker to bypass size checks potentially resulting in a denial of service

A Time-of-check time-of-use (TOCTOU) race condition in the SMM communications buffer could allow a privileged attacker to bypass input validation and perform an out of bounds read or write, potentially resulting in loss of confidentiality, integrity, or availability.

Improper input validation in the SMM handler could allow an attacker with Ring0 access to write to SMRAM and modify execution flow for S3 (sleep) wake up, potentially resulting in arbitrary code execution.

Improper removal of sensitive information before storage or transfer in AMD Crash Defender could allow an attacker to obtain kernel address information potentially resulting in loss of confidentiality.

A NULL pointer dereference in AMD Crash Defender could allow an attacker to write a NULL output to a log file potentially resulting in a system crash and loss of availability.

Improper input validation for DIMM serial presence detect (SPD) metadata could allow an attacker with physical access, ring0 access on a system with a non-compliant DIMM, or control over the Root of Trust for BIOS update, to bypass SMM isolation potentially resulting in arbitrary code execution at the SMM level.

Improper input validation in the GPU driver could allow an attacker to exploit a heap overflow potentially resulting in arbitrary code execution.

Improper validation of an array index in the AND power Management Firmware could allow a privileged attacker to corrupt AGESA memory potentially leading to a loss of integrity.

Incomplete cleanup after loading a CPU microcode patch may allow a privileged attacker to degrade the entropy of the RDRAND instruction, potentially resulting in loss of integrity for SEV-SNP guests.

A transient execution vulnerability in some AMD processors may allow an attacker to infer data in the L1D cache, potentially resulting in the leakage of sensitive information across privileged boundaries.

A transient execution vulnerability in some AMD processors may allow an attacker to infer data from previous stores, potentially resulting in the leakage of privileged information.

A transient execution vulnerability in some AMD processors may allow a user process to infer the control registers speculatively even if UMIP feature is enabled, potentially resulting in information leakage.

A transient execution vulnerability in some AMD processors may allow a user process to infer TSC_AUX even when such a read is disabled, potentially resulting in information leakage.

Incomplete cleanup in the ASP may expose the Master Encryption Key (MEK) to a privileged attacker with access to the BIOS menu or UEFI shell and a memory exfiltration vulnerability, potentially resulting in loss of confidentiality.

Insufficient checking of memory buffer in ASP Secure OS may allow an attacker with a malicious TA to read/write to the ASP Secure OS kernel virtual address space, potentially leading to privilege escalation.

Lack of stack protection exploit mechanisms in ASP Secure OS Trusted Execution Environment (TEE) may allow a privileged attacker with access to AMD signing keys to c006Frrupt the return address, causing a stack-based buffer overrun, potentially leading to a denial of service.
