Caution

Menggunakan metode ini UnsafeQueueNativeOverlapped secara tidak sengaja dapat membuka lubang keamanan. Keamanan akses kode mendasarkan pemeriksaan izinnya pada izin semua pemanggil di tumpukan. Saat pekerjaan diantrekan pada utas kumpulan utas menggunakan UnsafeQueueNativeOverlapped, tumpukan utas kumpulan utas tidak memiliki konteks pemanggil yang sebenarnya. Kode berbahaya mungkin dapat mengeksploitasi ini untuk menghindari pemeriksaan izin.
