CVE-2010-4079

Published: 29 November 2010

The ivtvfb_ioctl function in drivers/media/video/ivtv/ivtvfb.c in the Linux kernel before 2.6.36-rc8 does not properly initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via an FBIOGET_VBLANK ioctl call.

From the Ubuntu security team

Dan Rosenberg discovered that the ivtv V4L driver did not correctly initialize certian structures. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy.
