Descriptions
The assoc_array_insert_into_terminal_node function in lib/assoc_array.c in the Linux kernel before 4.5.3 does not check whether a slot is a leaf, which allows local users to obtain sensitive information from kernel memory or cause a denial of service (invalid pointer dereference and out-of-bounds read) via an application that uses associative-array data structures, as demonstrated by the keyutils test suite.
La función assoc_array_insert_into_terminal_node en lib/assoc_array.c en el kernel de Linux en versiones anteriores a 4.5.3 no comprueba una ranura en una hoja, lo que permite a usuarios locales obtener información sensible de la memoria del núcleo o provocar una denegación de servicio (referencia a un puntero no válido y lectura fuera de rango) a través de una aplicación que utiliza estructuras de datos asociative-array, como lo demuestra el conjunto de pruebas de keyutils.
