Not everyone using Ubuntu is on enterprise support, right?
The entire OS is open source. I've lost count of the number of times in my career when something like this has happened and even with the luxury of enterprise support, we couldn't wait. Just find a fast way to patch until support shows up with an official solution.
Amazing I keep getting downvoted for a comment like this on an OSS Linux distribution that you can fix yourself live in production without someone getting in your way.
