CVE-2026-72137

CVE-2026-72137 : In the Linux kernel, the xfrm nat_keepalive path suffers a double-free of the keepalive skb on send errors. Specifically, nat_keepalive_send() frees the skb when IPv4/IPv6 send helpers report an error, but after ip_build_and_send_pkt() or ip6_xmit() takes ownership the cleanup is...
