NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-bootwrapper package and not the kernel-bootwrapper 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.
