** Description changed:
- [ns: user namespaces panic -- lack of internal consistency of a data
- structure]
+ The fs_pin implementation in the Linux kernel before 4.0.5 does not
+ ensure the internal consistency of a certain list data structure, which
+ allows local users to cause a denial of service (system crash) by
+ leveraging user-namespace root access for an MNT_DETACH umount2 system
+ call, related to fs/fs_pin.c and include/linux/fs_pin.h.
