What is CVE-2014-7970?

The vulnerability in the Linux kernel's pivot_root implementation allows local users to trigger a denial of service by creating a mount-tree loop. This occurs when invalid dot values are provided in the pivot_root system call, leading to improper handling of chroot directory locations. Exploiting this vulnerability could disrupt system operations and lead to service unavailability.
