Need nudge =)
These challenge freaks me out…

I could also use a hint…

was trying something along the lines of PayloadsAllTheThings/Linux - Privilege Escalation.md at master · swisskyrepo/PayloadsAllTheThings · GitHub, without success

same here, tried all payloads and nothing…

I’ve tried many thing but without any success. I have the feeling it is some p**e magic but I could not find the correct solution.
The other idea I have in mind would require some custom compiled .so, but I think that is too complex for an easy challenge.
