NVD Description

Note: Versions mentioned in the description apply only to the upstream dtrace-modules-4.1.12-37.6.2.el7uek package and not the dtrace-modules-4.1.12-37.6.2.el7uek package as distributed by Oracle. See How to fix? for Oracle:7 relevant fixed versions and status.

The key_reject_and_link function in security/keys/key.c in the Linux kernel through 4.6.3 does not ensure that a certain data structure is initialized, which allows local users to cause a denial of service (system crash) via vectors involving a crafted keyctl request2 command.
