For now,\nproc_dou8vec_minmax() itself is tolerant to a data-race, but we still\nneed to add annotations on the other subsystem's side."},{"lang":"es","value":"En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: sysctl: Se corrigen las ejecuciones de datos en proc_dou8vec_minmax(). Se accede a una variable sysctl de forma concurrente y siempre existe la posibilidad de una ejecución de datos. Por lo tanto, todos los lectores y escritores necesitan una protección básica para evitar la rotura de la carga o el almacenamiento. Este parche cambia proc_dou8vec_minmax() para que utilice READ_ONCE() y WRITE_ONCE() internamente para corregir las ejecuciones de datos en el lado de sysctl.
