Since there is no vulnerability, there is no exploit mechanism. The steps below are hypothetical, based on the possibility of a vulnerability that never materialized:
Step 1: Initial Research: A researcher identifies a potential vulnerability.
Step 2: CVE Reservation: The researcher reserves a CVE ID to track the potential vulnerability.
Step 3: Vulnerability Analysis: The researcher investigates the potential vulnerability further.
Step 4: No Exploitation: The researcher determines the vulnerability is not exploitable, is fixed by the vendor, or decides not to disclose.
Step 5: CVE Rejection: The CVE is rejected because no vulnerability disclosure occurred.
