Red Hat Bugzilla – Bug 1249442
CVE-2015-4176 kernel:deletion of a file or directory could unmount and reveal data under a mount point.
Last modified: 2017-08-25 08:26:17 EDT
A flaw was found in the Linux kernel where the deletion of a file or directory could
trigger an unmount and reveal data under a mount point. This flaw was inadvertantly
introduced with the new feature of being able to lazily unmount a mount tree when
using filesystem user namespaces.
