ELI5 what does this mean for the average Linux user? I run a few Ubuntu 22.04 systems (yeah yeah, I know, canonical schmanonical) - but they aren’t bleeding edge, so they shouldn’t exhibit this vulnerability, right?
In this case I think that's just Fedora and Debian Sid users or so.
The backdoor only activates during DEB or RPM builds, and was quickly discovered so only rolling release distros using either package format were affected.
Not regular Fedora, though, it was only in Fedora Rawhide and Fedora 41, so very very early, bleeding edge distributions. Nothing that a regular Fedora user would be using.
