Description
drivers/media/video/v4l2-compat-ioctl32.c in the Video4Linux (V4L) implementation in the Linux kernel before 2.6.36 on 64-bit platforms does not validate the destination of a memory copy operation, which allows local users to write to arbitrary kernel memory locations, and consequently gain privileges, via a VIDIOCSTUNER ioctl call on a /dev/video device, followed by a VIDIOCSMICROCODE ioctl call on this device.

Remediation
Red Hat statement
This issue did not affect the versions of the Linux kernel as shipped with Red Hat Enterprise Linux 3 and 4 as they did not include the upstream commit eb4eeccc that introduced the problem. It did not affect Red Hat Enterprise Linux 5 and Red Hat Enterprise MRG as they did not provide support for the Stradis driver that uses the vulnerable compat code for VIDIOCSMICROCODE. As a preventive measure, we have removed the vulnerable code in Red Hat Enterprise Linux 5 via https://rhn.redhat.com/errata/RHSA-2010-0839.html. We plan to remove the vulnerable code in a future kernel update in Red Hat Enterprise MRG.
