Описание
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.
An information leak flaw was found in the way the Linux kernel handled media device enumerate entities IOCTL requests. A local user able to access the /dev/media0 device file could use this flaw to leak kernel memory bytes.
Отчет
This issue does not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 5, Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG 2.
