CVE-2026-72248

The CVE-2026-72248 entry pertains to the Linux kernel netfilter flowtable: IPIP tunnels with direct xmit can crash the tunnel transmit path due to missing dst_entry when checking headroom and setting iph->frag_off. The workaround/patch moves dst_cache and dst_cookie out of the runtime union so...
