CVE-2016-7914 · HIGH Severity

AV:N/AC:M/AU:N/C:C/I:N/A:N

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.
