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.

CVE-2017-9059 kernel: Module reference leak due to improper shut down of callback channel on umount
A leakage of module reference and kernel daemon in NFSv4 when NFSv4 mounts are made and then all outstanding NFSv4 mounts are removed. Local attackers with permission to mount NFS filesystems can potentially cause DoS by running the system out of resources.
Fixed by following patches:
