Description
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_ct: drop pending enqueued packets on removal
Packets sitting in nfqueue might hold a reference to:
- templates that specify the conntrack zone, because a percpu area is
used and module removal is possible.
- conntrack timeout policies and helper, where object removal leave
a stale reference.
Since these objects can just go away, drop enqueued packets to avoid
stale reference to them.
If there is a need for finer grain removal, this logic can be revisited
to make selective packet drop upon dependencies.
