JSON

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.
