What it is

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.
