Potential Security Vulnerability in TEE Could Lead to Denial of Service

CVE-2021-46746

Summary

A vulnerability exists in the ASP Secure OS Trusted Execution Environment (TEE) due to inadequate stack protection mechanisms. This flaw could be exploited by a privileged attacker who has access to AMD signing keys to manipulate the return address, leading to a stack-based buffer overrun. Such an attack may result in a denial of service, compromising the security and functionality of the affected systems. Organizations using AMD's TEE should implement necessary mitigations to protect against potential exploitation.
