How to fix?

Upgrade RHEL:7 kernel-doc to version 0:3.10.0-123.4.2.el7 or higher.
This issue was patched in RHSA-2014:0786.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-doc package and not the kernel-doc package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The raw_cmd_copyin function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not properly handle error conditions during processing of an FDRAWCMD ioctl call, which allows local users to trigger kfree operations and gain privileges by leveraging write access to a /dev/fd device.
