Exploit TEE Vulnerability
A malicious app or other attack vector could be used to exploit vulnerabilities in code running within the Trusted Execution Environment (TEE) . The adversary could then obtain privileges held by the TEE potentially including the ability to access cryptographic keys or other sensitive data . Escalated operating system privileges may be first required in order to have the ability to attack the TEE . If not, privileges within the TEE can potentially be used to exploit the operating system .
