CVE-2011-0711

Published: 01 March 2011

The xfs_fs_geometry function in fs/xfs/xfs_fsops.c in the Linux kernel before 2.6.38-rc6-git3 does not initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via an FSGEOMETRY_V1 ioctl call.

From the Ubuntu security team

Dan Rosenberg discovered that XFS did not correctly initialize memory. A local attacker could make crafted ioctl calls to leak portions of kernel stack memory, leading to a loss of privacy.
