CVE-2011-2909

Published: 06 October 2011

The do_devinfo_ioctl function in drivers/staging/comedi/comedi_fops.c in the Linux kernel before 3.1 allows local users to obtain sensitive information from kernel memory via a copy of a short string.

From the Ubuntu security team

Vasiliy Kulikov discovered that the Comedi driver did not correctly clear memory. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy.
