At large companies with politics and bureaucracies you can't really just come in and create a PR for a bug you've found like you'd do in a smaller shop or a startup.

If the code is not responsibility of you (your team / department) all you can do is create work requests / JIRA tickets for people/team responsible for the code.

You wouldn't even have access to the repository or dev/test environments for the affected system most likely.

And it might just sit there for months until it eventually gets picked up and fixed. Or it will never be fixed.
