Insufficient input validation in the ASP (AMD
Secure Processor) bootloader may allow an attacker with a compromised Uapp or
ABL to coerce the bootloader into exposing sensitive information to the SMU
(System Management Unit) resulting in a potential loss of confidentiality and
integrity.

Failure to unmap certain SysHub mappings in
error paths of the ASP (AMD Secure Processor) bootloader may allow an attacker
with a malicious bootloader to exhaust the SysHub resources resulting in a
potential denial of service.

Improper syscall input validation in AMD TEE
(Trusted Execution Environment) may allow an attacker with physical access and
control of a Uapp that runs under the bootloader to reveal the contents of the
ASP (AMD Secure Processor) bootloader accessible memory to a serial port,
resulting in a potential loss of integrity.

Time-of-check Time-of-use (TOCTOU) in the
BIOS2PSP command may allow an attacker with a malicious BIOS to create a race
condition causing the ASP bootloader to perform out-of-bounds SRAM reads upon
an S3 resume event potentially leading to a denial of service.

Insufficient bounds checking in ASP (AMD Secure
Processor) may allow for an out of bounds read in SMI (System Management
Interface) mailbox checksum calculation triggering a data abort, resulting in a
potential denial of service.

Failure to validate the length fields of the ASP
(AMD Secure Processor) sensor fusion hub headers may allow an attacker with a
malicious Uapp or ABL to map the ASP sensor fusion hub region and overwrite
data structures leading to a potential loss of confidentiality and integrity.
