I have installed everything successfully without any errors. But Still get when I run this

It would be better if you give me some explanation about what's going on.
Thank you

I'm facing the same issued kindly tell me the solution @Gui774ume

Hey there 👋🏻

Thank you for reporting the bug. Please note that this repo was first and foremost a research project, we built it for a specific kernel version and environment and didn't plan any support for it. We wanted to prove that building a rootkit with eBPF was possible, not release an omnipotent one to the world.

That said, I'll try to have a look over the following weeks, but no promisses, I'm already swamped with my day job 😄

(in the meantime, if you want to prevent the panic, you could simply test that the remaining length of body in the parseNetworkDiscoveryOutput() function is at least 32 bytes in each iteration of the loop ...)

@Gui774ume Thank You for that. This repo helped me with my research.
