Amd: Security Vulnerabilities
Insufficient input validation in ASP may allow
an attacker with a compromised SMM to induce out-of-bounds memory reads within
the ASP, potentially leading to a denial of service.

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.
