CVE-2014-1739  (opens in a new tab)
CWE-200  (opens in a new tab)

How to fix?

Upgrade RHEL:7 kernel to version 0:3.10.0-123.13.1.el7 or higher.
This issue was patched in RHSA-2014:1971.

NVD Description

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

The media_device_enum_entities function in drivers/media/media-device.c in the Linux kernel before 3.14.6 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel memory by leveraging /dev/media0 read access for a MEDIA_IOC_ENUM_ENTITIES ioctl call.
