Congratulations on being able to run an LLM, less so on being able to read and comprehend anything. I'll keep it short as you've already wasted more of my time than what is warranted: 1) No need to CC security@ if you send it to public lists. That's in our documentation 2) Send a patch to fix an issue, that's also in our documentation. and most importantly: 3) This isn't a security issue at all. An application resizing a ring and getting a CQE or SQE mangled is NOT a security issue. It's just a bug. If you want to actually be useful, send a fix. And don't bother security@ for trivial bugs. -- Jens Axboe
