"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nsysctl: Fix out of bounds access for empty sysctl registers\n\nWhen registering tables to the sysctl subsystem there is a check to see\nif header is a permanently empty directory (used for mounts). This check\nevaluates the first element of the ctl_table. This results in an out of\nbounds evaluation when registering empty directories.\n\nThe function register_sysctl_mount_point now passes a ctl_table of size\n1 instead of size 0. It now relies solely on the type to identify\na permanently empty register.\n\nMake sure that the ctl_table has at least one element before testing for\npermanent emptiness."

"value": "En el kernel de Linux, se resolvi\u00f3 la siguiente vulnerabilidad: sysctl: corrige el acceso fuera de los l\u00edmites para registros sysctl vac\u00edos. Al registrar tablas en el subsistema sysctl, se verifica si el encabezado es un directorio permanentemente vac\u00edo (usado para montajes). Esta verificaci\u00f3n eval\u00faa el primer elemento de ctl_table. Esto da como resultado una evaluaci\u00f3n fuera de los l\u00edmites al registrar directorios vac\u00edos. La funci\u00f3n Register_sysctl_mount_point ahora pasa un ctl_table de tama\u00f1o 1 en lugar de tama\u00f1o 0. Ahora se basa \u00fanicamente en el tipo para identificar un registro permanentemente vac\u00edo. Aseg\u00farese de que ctl_table tenga al menos un elemento antes de probar el vac\u00edo permanente."
