Description Prasad Pandit 2014-06-16 10:45:12 UTC 
Linux kernel built with the Multimedia support(CONFIG_MEDIA_SUPPORT) to enable
web-cam, video grabber devices, is vulnerable to an information leakage flaw.
It could occur while doing an ioctl(2) call on a media device file.

A user/process able to access the /dev/media0 device file could use this flaw
to leak kernel memory bytes.
