CVE-2026-53001

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.
