I came across this error after performing a regular system update on CentOS 7. Although it's a rather generic looking error message it turned out to be quite a trivial problem.
The pfring driver (provided by daq_pfring) had been compiled against the latest kernel version - however for whatever reason an older kernel was being loaded by default by the bootloader.
This can be evidenced by running:
uname -r
and a rpm -qa | grep kernel
To correct this issue:
grub2-set-default 0 # presuming menu item 0 is the kernel you want listed in: /boot/efi/EFI/centos/grub.cfg (which is usually the case.)
and then confirm with:
grub2-editenv list
Restart the machine and then check the kernel / test snort again:
shutdown -r now
sudo service snort status
