Ubuntu just got an update to face the meltdown problem, and the patches working fine so far on my test systems.
You can check (similar like on Windows) your systems for the hole via the spectre-meltdown-checker. Ubuntu called the announcement article simply “SpectreAndMeltdown” which lists CVE-2017-5715, CVE-2017-5753, CVE-2017-5754 aka Spectre and Meltdown.
The listed timeline shows that it only take one month to fix the issue, from the notification to a final fix, that’s pretty much okay I say. Together with the hole fixes, the NVIDIA driver was also updated to avoid some holes in the graphic drivers, because nVidia recently fixed USN-3521-1.
Most of all systems are now patched, there some problems here and there but overall it got really quick fixed, there still some open questions and the OEM’s need to deliver new BIOS updates but I think Spectre and Meltdown got the needed attention to make a wakeup call.
Hopefully we all learned something and it’s always good to be a bit sceptical.
