CVE-2016-7914
Last modified
CVE-2016-7914 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 2.04% chance of exploitation in the next 30 days.
