mdeslaur raised some good points about ksmbd that I think are compelling enough to remove it from this blocklist:
- it doesn't match the "insert a shady usb" attack vector - my opinion on it might be overly shaded from 2021 status https://lore.kernel.org/lkml/202109221850.003A16EC1@keescook/#t and not reflective of the years of effort since - it's on the way up, the others are on the way down furthermore, - since it's not really a filesystem in the way the others are filesystems, even if we still decide to blocklist it in a future release, an administrator might not "look" for it in this specific file. Are there any other changes that we should consider before we upload this?

This is cool, it's part of what makes Linux so flexible and helped bring Linux to the mainstream. However, quality of filesystem implementations varies wildly and the upstream kernel community doesn't consider flaws in filesystems to be security issues: https://lore.kernel.org/linux- fsdevel/20250407-biegung-furor-e7313ca9d712@brauner/ Ubuntu has decided to make it easy for users to mount filesystems, for better or for worse. The filesystems that have had less dedicated bug hunting bring significant risk to Ubuntu users. We can make it harder to mount these filesystem types without affecting most Ubuntu users through some simple module blocklisting. System administrators can still enable these other filesystem types with relatively easy efforts and everyone else will have reduced risk of ring 0 privilege escalation issues.
