CVE-2016-7914

Priority
Medium
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.
Ubuntu-Description
It was discovered that an out of bounds read vulnerability existed in the
associative array implementation in the Linux kernel. A local attacker
could use this to cause a denial of service (system crash) or expose
sensitive information.
