CVE-2010-4074

Published: 29 November 2010

The USB subsystem in the Linux kernel before 2.6.36-rc5 does not properly initialize certain structure members, which allows local users to obtain potentially sensitive information from kernel stack memory via vectors related to TIOCGICOUNT ioctl calls, and the (1) mos7720_ioctl function in drivers/usb/serial/mos7720.c and (2) mos7840_ioctl function in drivers/usb/serial/mos7840.c.

From the Ubuntu Security Team

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