Exactly that, a lot of pieces of software have been open source and had vulnerabilities or had problems for years.
An example is CVE-2021-3156 in Sudo, it has there for 10 years and nobody noticed.

* CVE-2021-3156:

Yes, great example.

CHECKSUM files and package signing keys. Each stable RPM package published by the Fedora Project is signed with a GPG signature.

dnf asks you importing an GPG key.

We use many virtual machines (network bridge) here for different purposes. In the VM ONLINE the .iso spyware image see only several browser, zero private / personal data and wrong hardware information.

The Host .iso spyware image is always offline (sometimes security updates). An offline .iso spyware image can neither be spied on nor attacked. ʕ•ᴥ•ʔ

Both .iso spyware images (host + guest) see only Tor relays. Router allows only Tor traffic.

Private data is in my Nitrokey Storage or DVD-RAM or external NVMe SSD. One Panasonic DVD-RAM in a drawer cannot be spied on. There is another VM - the name of this VM is OFFLINE (removed the virtual network interface). How do you attack a VM without a virtual network device (host is offline too)???

Or rather, mega right.
All software in virtual machines. Never run software in the Host OS. Host is offline, guest use network bridging.

The last problems: hardware, hypervisor, virtualization software bugs / backdoors.

Powerless, i have no plan against backdoors. Theoretically you would have to use two routers with different hardware to protect yourself from it. In the hope that one of the routers does not have a backdoor.

Backdoorfree is only Nitrokey Storage and one DVD-RAM (no firmware).
