Description
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.
