Improper Control of a Resource Through its Lifetime

Resources, whether memory, files, database connections, or objects, come with inherent rules for safe handling. When code ignores these rules—like using a resource before it's fully initialized or after it's been marked for cleanup—it creates unstable conditions that attackers can exploit. Even without formal documentation, fundamental programming principles apply. You should never use an object before its constructor finishes, and you must avoid referencing resources scheduled for destruction. Consistent, disciplined management at each lifecycle stage is essential for preventing crashes, data corruption, and security breaches.
