Name of the Vulnerable Software and Affected Versions: Intel(R) SGX DCAP software versions prior to 1.6

Description: The issue is related to an improper conditions check in the Intel(R) SGX DCAP software, which may allow an unauthenticated user to potentially enable denial of service via adjacent access. This is due to insufficient input validation, allowing a remote attacker to cause a denial of service.
