Hello, We are a small hacker group from Denmark. We have during the last 1/2 year been reverse engineering the iRISC architecture used on the NVIDIA/Mellanox ConnectX NICs. We have given a presentation on the subject at the hacker camp Bornhack in Denmark and made our research public. We are writing to you because multiple attendees have suggested we contact you. The research we have done is available here: Git repos: https://github.com/irisc-research-syndicate Slides: https://github.com/irisc-research-syndicate/documentation/blob/master/NVIDIA_Mellanox%20ConnectX-5(Bornhack%202024).pdf Video of the talk might become available here at some point after the camp: https://media.ccc.de/b/conferences/bornhack To the NVIDIA/Mellanox people: Is there any way that we can get access to documentation(or even source code) related to iRISC or ConnectX? We currently have no idea about the impact of what we have published today, and what bugs or vulnerabilities people(us or others) are able to get from the resear ch we have done. Are you interested in collaborating in further vulnerability research? /Jonas Rudloff, Tethys Svensson, Kristoffer Søholm
