In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: move hardware offload step after building the chain blob
Allocate the chain blob before the ruleset offload to reduce chances of
entering an inconsistent state where the offloaded ruleset in the nic
and the software ruleset differ.
