The issue is related to a null-pointer dereference in the libbpf component of the Linux kernel. Specifically, in the `bpf objec load prog()` function, there is no guarantee that `obj->btf` is non-NULL when passed to `btf fd()`, which does not perform any checks before dereferencing its argument. This can lead to segmentation fault errors when trying to load programs without BTF information, for example, in bpftool.
