Assuming you have at least as many CVE's as IP addresses, I would read in the CVE's, shuffle them, and then assign the first IP address to the first CVE, the second IP address to the second CVE, etc.

Unless the list of CVE's is so large you cannot slurp them into memory, this should work reasonably fast.

Quick, dirty and untested code: 

use 5.010;
use strict;
use warnings;
use Scalar::Util qw [shuffle];
my @ips  = `cat ip_addresses`;
my @cves = shuffle `cat cves`;
chomp @ips;
chomp @cves;
while (@ips) {
    say "IP address $_ gets CVE ", shift @cves;
}
