"...system they're working on"
"I know there's a security issue... [Nobody] will tell me what it is"
"I don't have any information..."
This might sound crazy, but have you tried looking at "your" code base?
It's just genuinely baffling to read stuff like this.
I can't imagine feeling so helpless on something I was supposedly "working on".
"system they're working on" refers to the actual physical hardware.
Yes, I look at the code regularly, and a significant portion is hand written, especially the performance critical sections.
A security issue I haven't been able to track came up in automated code reviews. Maybe you're such a savant that you can crack any security issue in a codebase you're working on, but the last few months of critical security bugs in infrastructure with the most experienced and capable maintainers in the world should at least humble you a little.
