- Mitigation guidance
- To mitigate this issue, applications should avoid initializing libkcapi handles with the `KCAPI_INIT_AIO` flag, preferring synchronous interfaces instead. If the real AIO path must be enabled, applications must ensure that `outiov` buffers are not immediately freed or reused after an error return, allowing all kernel completions to finish. This operational control prevents delayed kernel writes into potentially reallocated or freed memory.
