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 NFPROTOUNSPEC in more extensions" to allow ipv4 and ipv6 only. - xtmac - xtowner - xtphysdev...

CVE-2026-53001

CVE-2026-53001 in the Linux kernel concerns the netfilter xtables extensions. The fix partially reverts a previous change to restrict several matches (xt_mac, xt_owner, xt_physdev) to the inet family (IPv4/IPv6), with xt_realm limited to IPv4. The intent is to apply these restrictions and avoid u...
