Attack profile from CVSS 3.0 · NVD. Fix status from CNA and Red Hat. Impact type from CWE-125, CWE-476 and the CVSS impact.

Summary

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.
