The NFSv4 implementation in the Linux kernel through 4.11.1 allows local users to cause a denial of service (resource consumption) by leveraging improper channel callback shutdown when unmounting an NFSv4 filesystem, aka a module reference and kernel daemon leak.
The product does not release or incorrectly releases a resource before it is made available for re-use.
