Yup, I checked on the Source RPM and the affected code it's in fact there, so it must have been backported as you've said. Thanks.

It says RHEL 8 is affected, but RHEL 8 comes with kernel 4.18, and according to https://seclists.org/oss-sec/2... the bug was introduced in 5.4-rc1, so I believe RHEL based systems (at least on stable version 8-based distros, like RHEL, Rocky or Alma) are not affected.

What about a data center in a shipping container... From 2007 (or earlier)? http://en.wikipedia.org/wiki/S...

I've been using Linux every day for most of my life, and I've used this key combination once or twice.
