Original GitHub issue: https://github.com/amnezia-vpn/amneziawg-linux-kernel-module/issues/266

Ubuntu 26.04.1 LTS, kernel 7.0.0-38
error because of compat/compat.h
Look at lines about 1450

#if LINUX_VERSION_CODE < KERNEL_VERSION(7, 1, 5)
#include <net/udp_tunnel.h>
#define setup_udp_tunnel_sock(net, sk, sock_cfg) setup_udp_tunnel_sock(net, sk->sk_socket, sock_cfg)
#define udp_tunnel_sock_release(sk) udp_tunnel_sock_release(sk->sk_socket)
#endif

First define is not needed with the kernel. It has already new interface. So build fails with the define and passes if I comment it. Second one is needed.
I think it should be something like the next one here

#if LINUX_VERSION_CODE < KERNEL_VERSION(7, 1, 5)
#include <net/udp_tunnel.h>
#if LINUX_VERSION_CODE < KERNEL_VERSION(7, 0, 0)
#define setup_udp_tunnel_sock(net, sk, sock_cfg) setup_udp_tunnel_sock(net, sk->sk_socket, sock_cfg)
#endif
#define udp_tunnel_sock_release(sk) udp_tunnel_sock_release(sk->sk_socket)
#endif
