CVE-2026-72256

In the Linux kernel, the following vulnerability has been resolved: netfilter: xtcluster: reject template conntracks in hash match xtclustermt treats any non-NULL nfctget result as a fully initialized conntrack and passes it to xtclusterhash. This causes a state confusion bug when the raw table C...

CVE-2024-50038

CVE-2024-50038 : Linux kernel fix for netfilter xtables UNSPEC handling. The patch ensures matches/targets no longer assume skb_network_header() validity when UNSPEC is used, and restricts registration to NFPROTO_IPV4/NIPv6 (and ARP for MARK target). This prevents ebtables traversal from misproce...
