We've run into multiple Linux kernel f2fs data corruption issues before Android 14 while testing new Linux kernel LTS revisions. We avoided any of the serious issues slipping past our internal testing. The only one to make it into the Alpha channel only caused update rollback.

Our first experimental release based on Android 14 was published on October 6th. We think we already had this issue resolved for that release:

We’ve made additional fixes for upstream user profile issues still impacting the stock Pixel OS since then too
