Summary
netfilter: conntrack: re-fetch conntrack after insertion
Details

In the Linux kernel, the following vulnerability has been resolved:

netfilter: conntrack: re-fetch conntrack after insertion

In case the conntrack is clashing, insertion can free skb->nfct and set skb->nfct to the already-confirmed entry.

This wasn't found before because the conntrack entry and the extension space used to free'd after an rcu grace period, plus the race needs events enabled to trigger.
