"Users who are concerned can rest assured that security updates have been rolled out for all vulnerabilities"
It's good that there are fixes for all of them. They sound like mostly software issues, some fixed a while ago.
Like XTU was fixed no later than Oct-8-2023, Arc drivers no later than Dec-15-2023, Intel Proset wireless& bluetooth on Jan 10th - 2024, some old chipset installation utility fixed on April 10 - 2023, Intel graphics command was fixed before the Arc driver was.
I'm going by when the fixed software was available for download by searching for it. It might have been available earlier than some site like Techspot posted the download, but probably not by too much.
These are all that I could think might affect me, long fixed, maybe somebody is just doing some security reporting housekeeping.
