Description

In the Linux kernel, the following vulnerability has been resolved:

netfilter: xtables: restrict several matches to inet family

This is a partial revert of:

commit ab4f21e6fb1c ("netfilter: xtables: use NFPROTO_UNSPEC in more extensions")

to allow ipv4 and ipv6 only.

- xt_mac - xt_owner - xt_physdev

These extensions are not used by ebtables in userspace.

Moreover, xt_realm is only for ipv4, since dst->tclassid is ipv4 specific.
