Vulnerability CVE-2017-9059


Published: 2017-05-18

Description:
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.

Vendor: Linux
Product: Linux kernel 
Version: 4.11.1;
