Doc Text:
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.

Description Vladis Dronov 2016-12-15 02:14:31 EST 
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.
