Just my two cents on this, I hope Brian does not mind.
The article from BC (Bleeping Computer) should not strike fear into the hearts of most users.
While the threat is real, it may not affect most, if not all of our Members and Users.
It does not affect Linux Mint users, unless you have actively installed the package needrestart.
For all users of Debian-based distros, you can check with
You
may find in the output a couple of references to needrestart, needrestart.mo, needrestart-session, even a desktop file, but these are provided should you actively have chosen to use needrestart on your computer.
Unless you have the actual binary file, /usr/sbin/needrestart you have no need for concern.
It does not ship installed with Ubuntu Desktop and its community flavours. I cannot speak for Ubuntu Server, by all means check.
If Ubuntu users find
/usr/sbin/needrestart
has been installed on your computer, and you did not do so actively, then it may have been suggested and installed by the package
unattended-upgrades
(which I disable on all my 'buntu-based distros when I first install, if it is present)
needrestart can also be used in Debian, Fedora, and Arch, so it is worth checking in those distros, and keep current with updates.
