CVE-2014-2309 - ICMPv6 Router Advertisement flood Denial of service

CVE reference: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-2309

I guess it works only if your Linux box accepts IPV6 router advertisement packets. Do you want to check if your Linux accepts router advertisement packets?

Check the kernel settings for IPV6:

Check in /proc/sys/net/ipv6/conf//accept_ra setting, if 0 means disabled, if 1 means setting is enabled.
