Make io_queue_iowq() fail requests in this case.\n\nNote that it also checks PF_KTHREAD, because the user can first close\na DEFER_TASKRUN ring and shortly after kill the task, in which case\n->iowq check would race."},{"lang":"es","value":"En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: io_uring: comprueba si iowq se elimina antes de que se pueda ejecutar la tarea de cola work después de que la tarea haya pasado por la terminación io_uring, ya sea la ejecución final de task_work o la ruta de respaldo. En este caso, la tarea work encontrará que ->io_wq ya se ha eliminado y se ha anulado, lo que es un problema si luego intenta reenviar la solicitud a io_queue_iowq(). Haz que io_queue_iowq() falle las solicitudes en este caso.
