      "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nsysctl: Fix data races in proc_douintvec_minmax().\n\nA sysctl variable is accessed concurrently, and there is always a chance\nof data-race.  So, all readers and writers need some basic protection to\navoid load/store-tearing.\n\nThis patch changes proc_douintvec_minmax() to use READ_ONCE() and\nWRITE_ONCE() internally to fix data-races on the sysctl side.  For now,\nproc_douintvec_minmax() itself is tolerant to a data-race, but we still\nneed to add annotations on the other subsystem's side."

      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: sysctl: Se corrigen las ejecuciones de datos en proc_douintvec_minmax(). Se accede a una variable sysctl de forma concurrente y siempre existe la posibilidad de una ejecuci\u00f3n de datos. Por lo tanto, todos los lectores y escritores necesitan una protecci\u00f3n b\u00e1sica para evitar la rotura de la carga o el almacenamiento. Este parche cambia proc_douintvec_minmax() para que utilice READ_ONCE() y WRITE_ONCE() internamente para corregir las ejecuciones de datos en el lado de sysctl. Por ahora, proc_douintvec_minmax() en s\u00ed es tolerante a una ejecuci\u00f3n de datos, pero a\u00fan necesitamos agregar anotaciones en el lado del otro subsistema."
