So, all readers and writers need some basic protection to\navoid load/store-tearing.\n\nThis patch changes proc_dou8vec_minmax() to use READ_ONCE() and\nWRITE_ONCE() internally to fix data-races on the sysctl side. 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().

Por lo tanto, todos los lectores y escritores necesitan una protecci\u00f3n b\u00e1sica para evitar la rotura de la carga o el almacenamiento.
