NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-headers package and not the kernel-headers package as distributed by RHEL.

The keyring_search_aux function in security/keys/keyring.c in the Linux kernel through 3.14.79 allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a request_key system call for the "dead" type.
