You could boot from some Live distro (Fedora Workstation Live will do),
mount your root partition inside /mnt/fedora/root and do something like:
find /mnt/fedora/root/usr/bin/ -type f -exec chmod 755 {} \;
but I fear manually searching for every broken permission in every
directory would take days. If You manage to fix a host enough to
work, try to reinstall packages with dnf, which will set correct
permissions. 775 is a little more than needed.
Or You could install Fedora on some virtual machine, update it and
rsync /usr dir onto Your broken installation.
Sort of:
rsync -vaxAXHSz --delete --dry-run /usr ip.of.broken.host:/usr
and then
rsync -vaxAXHSz --delete /usr ip.of.broken.host:/usr
I'll bet that's not enough to fix it, but it would be fun to try. If
you have time for it. If not, just reinstall.
