You can view information about the pulled commits with:
ostree log fedora:fedora/41/x86_64/silverblue
Afterwards you can see what would be downgraded betweeen booted deployment and an old commit with:
rpm-ostree db diff <old-commit>
Do this compare until you find a kernel downgrade to the version you would consider is working for you.
No more dangerous than staying on older commits without upgrading. You would be missing security fixes that were pushed in the meantime.
An alternative would be to override the kernel with the command sudo rpm-ostree override replace <http or local file paths of kernel packages to be downgraded>, e.g.:
sudo rpm-ostree override replace https://koji.fedoraproject.org/koji/buildinfo?buildID=2673955
You would need to reset the override when your fix has been landed in the repos with
sudo rpm-ostree override reset <kernel packages that have been overridden>.
