⚠️ Risk & Real-World Impact
Worst Case
An authenticated attacker could gain elevated privileges on the local system, potentially compromising the entire system.
Likely Case
Local authenticated users could escalate privileges to gain unauthorized access to sensitive SGX enclave data or system resources.
If Mitigated
With proper access controls and patching, the risk is limited to authorized users who would need to bypass additional security measures.
🎯 Exploit Status
Requires local authenticated access and knowledge of SGX SDK. No public exploits known at this time.
