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

A buffer overflow in the AMD Secure Processor (ASP) bootloader could allow an attacker to overwrite memory, potentially resulting in privilege escalation and arbitrary code execution.

Improper syscall input validation in ASP (AMD Secure Processor) may force the kernel into reading syscall parameter values from its own memory space allowing an attacker to infer the contents of the kernel memory leading to potential information disclosure.

Improper system call parameter validation in the Trusted OS may allow a malicious driver to perform mapping or unmapping operations on a large number of pages, potentially resulting in kernel memory corruption.

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 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 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.

Failure to validate the address and size in TEE (Trusted Execution Environment) may allow a malicious x86 attacker to send malformed messages to the graphics mailbox resulting in an overlap of a TMR (Trusted Memory Region) that was previously allocated by the ASP bootloader leading to a potential loss of integrity.

Insufficient parameter validation while allocating process space in the Trusted OS (TOS) may allow for a malicious userspace process to trigger an integer overflow, leading to a potential denial of service.

Improper register access control in ASP may allow a privileged attacker to perform unauthorized access to ASP’s Crypto Co-Processor (CCP) registers from x86 resulting in potential loss of control of cryptographic key pointer/index leading to loss of integrity or confidentiality.

Improper key usage control in AMD Secure Processor (ASP) may allow an attacker with local access who has gained arbitrary code execution privilege in ASP to extract ASP cryptographic keys, potentially resulting in loss of confidentiality and integrity.

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.

Insufficient input validation in the ABL may allow a privileged attacker with access to the BIOS menu or UEFI shell to tamper with the structure headers in SPI ROM causing an out of bounds memory read and write, potentially resulting in memory corruption or denial of service.

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.

Insufficient access controls in ASP kernel may allow a privileged attacker with access to AMD signing keys and the BIOS menu or UEFI shell to map DRAM regions in protected areas, potentially leading to a loss of platform integrity.

A malicious attacker in x86 can misconfigure the Trusted Memory Regions (TMRs), which may allow the attacker to set an arbitrary address range for the TMR, potentially leading to a loss of integrity and availability.

An out of bounds memory write when processing the AMD PSP1 Configuration Block (APCB) could allow an attacker with access the ability to modify the BIOS image, and the ability to sign the resulting image, to potentially modify the APCB block resulting in arbitrary code execution.
