The ioqueue component may issue a double key unregistration after an attacker initiates a socket connection with specific settings and sequences. Such double key unregistration will trigger an integer overflow, which may cause ioqueue backends to reject future key registrations."

El componente ioqueue puede enviar una anulaci\u00f3n del registro de una clave doble despu\u00e9s de que un atacante inicie una conexi\u00f3n de socket con ajustes y secuencias espec\u00edficos.
