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...
