In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_compat: ebtables emulation must reject non-bridge targets
xtables targets return netfilter verdicts: NF_ACCEPT, NF_DROP, and so
on. ebtables targets return incompatible verdicts: EBT_ACCEPT,
EBT_DROP, ... We cannot allow fallback to NFPROTO_UNSPEC.
ebtables doesn't permit this since
11ff7288beb2 ("netfilter: ebtables: reject non-bridge targets")
but that commit missed the nft_compat layer.
