The weakness is caused due to the "xfs_ioc_fsgetxattr()" function in fs/xfs/linux-2.6/xfs_ioctl.c not properly initializing all members of a certain structure before copying it to userspace, which can be exploited to disclose kernel stack memory by sending XFS_IOC_FSGETXATTR IOCTLs. SOLUTION: Restrict access to trusted users only.
