CWE-200  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 2.6.38 or higher.

Overview

Affected versions of this package are vulnerable to Information Exposure. 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.
