CVE-2023-20514
HighSummary
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.
Risk Assessment
The risk for the organization includes the possibility of a privileged attacker gaining control over the trusted execution environment, potentially compromising the integrity and confidentiality of data processed within it.
Recommendation
It is recommended to immediately apply patches provided by AMD for affected systems and restrict privileged access to the minimum necessary for operation.
Other vulnerabilities in AMD Secure Processor
See all- CVE-2023-31323High
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.
- CVE-2025-29951High
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.
- CVE-2021-46747High
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.
