CVE-2010-3297

Published: 30 September 2010

The eql_g_master_cfg function in drivers/net/eql.c in the Linux kernel before 2.6.36-rc5 does not properly initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via an EQL_GETMASTRCFG ioctl call.

From the Ubuntu security team

Dan Rosenberg discovered that several network ioctls did not clear kernel memory correctly. A local user could exploit this to read kernel stack memory, leading to a loss of privacy.
