CVE-2011-0711: Linux Kernel

Low severity, CVSS 2.1. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

• Red Hat Enterprise Linux Desktop: version 5.0 only
