-Subject: [PATCH] ip_reass: Fix use after free
-
-Using ip_deq after m_free might read pointers from an allocation reuse.
-
-This would be difficult to exploit, but that is still related with
-CVE-2019-14378 which generates fragmented IP packets that would trigger this
-issue and at least produce a DoS.
