If an application ended up getting a partial wolfSSL_read() which is sometimes caused by a small user buffer  passed in, then called wolfSSL_shutdown for a bidirectional close and attempted to wolfSSL_read() again while the peer continues trying to send data during the shutdown it would lead to a state where a potential heap-use-after free happened.",
