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.

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.

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 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.

Insufficient input parameter sanitization in AMD Secure Processor (ASP) Boot Loader (legacy recovery mode only) could allow an attacker to write out-of-bounds to corrupt Secure DRAM potentially resulting in denial of service.

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.

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.

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 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.

Use of an uninitialized variable in the ASP could allow an attacker to access leftover data from a trusted execution environment (TEE) driver, potentially leading to loss of confidentiality.

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

Insufficient protections in System Management Mode (SMM) code may allow an attacker to potentially enable escalation of privilege via local access.
