CVE-2023-31323
HighSummary
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.
Risk Assessment
The risk includes memory safety violation, potentially leading to data disclosure, modification, or system disruption. An attacker may exploit this to escalate privileges or destabilize the system.
Recommendation
It is recommended to update AMD Secure Processor firmware to the latest patched version. Also, monitor AMD security advisories and apply recommended mitigations.
Other vulnerabilities in AMD Secure Processor
See all- CVE-2023-20514High
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.
- 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.
