Doc Text:
A flaw was found in wolfSSL. The side-channel protected T-Table implementation in wolfSSL up to version 5.6.5 protects against a side-channel attacker with cache-line resolution. In a controlled environment such as Intel SGX, an attacker can gain a per instruction sub-cache-line resolution, allowing them to break the cache-line-level protection.
