AMD Secure Processor vulnerabilities

Type confusion in the AMD Secure Processor (ASP) could allow an attacker to pass a malformed argument to the External Global Memory Interconnect Trusted Agent (XGMI TA) leading to a memory safety violation potentially resulting in loss of confidentiality, integrity, or availability.

The vulnerability in AMD Secure Processor (ASP) stems from improper handling of parameters, allowing a privileged attacker to pass an arbitrary memory value to functions in the trusted execution environment. This could lead to arbitrary code execution.

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

Insufficient granularity of access control in ASP (AMD Secure Processor) may allow an attacker with an untrusted user space application to map sensitive SMN apertures leading to a potential escalation of privileges.
