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.
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.
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.
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 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.
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.
An out of bounds write in the Linux graphics driver could allow an attacker to overflow the buffer potentially resulting in loss of confidentiality, integrity, or 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 AMD Graphics Driver could allow an attacker to supply a specially crafted pointer, potentially leading to arbitrary writes or denial of service.
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.
Improper input validation in the system management mode (SMM) could allow a privileged attacker to overwrite arbitrary memory potentially resulting in arbitrary code execution at the SMM level.
An out-of-bounds read in the ASP could allow a privileged attacker with access to a malicious bootloader to potentially read sensitive memory resulting in loss of confidentiality.
Improper isolation of shared resources on System-on-a-chip (SOC) could a privileged attacker to tamper with the contents of the PSP reserved DRAM region potentially resulting in loss of confidentiality and 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.
Insufficient clearing of GPU global memory could allow a malicious process running on the same GPU to read left over memory values potentially leading to loss of confidentiality.
