CVE-2016-7914

MEDIUM 5.5EPSS 2.04%

Does this matter?

Lower severity and a low EPSS score (2.04%). Track it; it rarely justifies an emergency change on its own.

Description

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.
