Time-of-check time-of-use vulnerability in the Crypto API Toolkit for Intel(R) SGX may allow a privileged user to potentially enable escalation of privilege via network access.

Weakness

The product checks the state of a resource before using that resource, but the resource’s state can change between the check and the use in a way that invalidates the results of the check. This can cause the product to perform invalid actions when the resource is in an unexpected state.
