netfilter: nft_compat: ebtables emulation must reject non-bridge targets
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.
