DHCP vulnerabilitiesRanked by how likely they are to be used.
DHCP is made by Isc. We track 25 published vulnerabilities listed under that exact name, across 45 versions. None of them is on the list of flaws known to be exploited today. Isc lists newer releases under their own names, such as DHCP Client, so check those pages too.
We keep watching the known-exploited list.
Is DHCP listed under other names? Yes.
Isc also lists DHCP under more specific names, such as DHCP Client. Flaws listed only under those names are counted on their own pages, not here. If you run one of these, open its page for its own exploited flaws.

Which DHCP flaws are most likely to be used?
Ranked by the latest exploit-likelihood forecast: the chance each flaw is used in an attack in the next 30 days. A high severity score on its own doesn't tell you that. Flaws shared by many other makers' products are left out.
