Hi,
no worries, this is nothing alarming. These are routine updates for the UEFI Secure Boot Forbidden Signature Database (DBX), a blocklist in your firmware. When a signed bootloader is found to have a security vulnerability, its signature gets added to the DBX so it can no longer be executed, even from a USB stick.
The three updates cover bootloaders from IGEL, DT Research, and Howyar, none of which are used by TUXEDO OS, so there is no impact on your running system.
Just apply them via your software center or run:
sudo fwupdmgr update
Then reboot and you're done!
Let us know if you have further questions.
TUXEDO
