CVE-2024-27397

In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: use timestamp to check for set element timeout Add a
timestamp field at the beginning of the transaction, store it in the
nftables per-netns area. Update set backend .insert, .deactivate and sync
gc path to use the timestamp, this avoids that an element expires while
control plane transaction is still unfinished. .lookup and .update, which
are used from packet path, still use the current time to check if the
element has expired. And .get path and dump also since this runs lockless
under rcu read size lock. Then, there is async gc which also needs to check
the current time since it runs asynchronously from a workqueue.
