Most customers running v14 who upgraded from previous versions are not affected because they are on the 3.16.0 and earlier kernels which are not affected.
Customers Who are Impacted
Customers running both the 4.9.0-6 kernel and NG Firewall v14.0 are affected. New installs of v14 are affected. Upgraded v14 installs where the customer manually switched to the new 4.9.0-6 kernel are also affected. However, customers who upgraded can reboot and select the old kernel and will no longer be affected.
