El código de generación de trampolín usa emit_addr_mov_i64() para emitir instrucciones para mover la dirección bpf_tramp_image a R0, pero emit_addr_mov_i64() asume que la dirección está en el espacio vmalloc() y usa solo 48 bits. Debido a que bpf_tramp_image se asigna usando kzalloc(), su dirección puede usar más de 48 bits, en este caso el trampolín pasará una dirección no válida a __bpf_tramp_enter/exit() provocando un bloqueo del kernel.
