# CVE-2026-72416

> 7.3 HIGH

## Beschreibung

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.
