Description Prasad J Pandit 2014-10-09 15:24:28 UTC
Linux kernel file system implementation is vulnerable to a DoS flaw. It could occur by doing umount(2) call from within user name spaces.

An unprivileged user/process could use this flaw to render the system unusable by making file system inaccessible.
