Unless you are missed the news. Bug found in OpenZFS causing data corruption, FreeBSD, Linux and illumos are all affected.
Some good news from bug tracker on OpenZFS
OpenZFS 2.2.2 and 2.1.14 released with fix in place. If you don’t get your OpenZFS direct from here, point your vendor at it.
Patch your systems!!

It looks like due to the older coreutils Ubuntu 22.04 LTS is unlikely to be affected as much. So if you’re on Ubuntu LTS and have not compiled it yourself, you might have dodged data corruption.
Would this corruption be caught by the checksumming?
No
This seems to affect ZFS >=2.2.0. Ubuntu 22.04 LTS is on ZFS 2.1.5
Nope!
OpenZFS through 2.1.13 and 2.2.x through 2.2.1 contain this bug.
This issue occurs less often in version 2.2.1, and in versions before 2.1.4, because of the default configuration in those versions.
From here
Weird. Reading the issue on GitHub I got the impression that it affects 2.2.0+.
Also I glanced something that the version of coreutils also contributes to the interaction.
E: Seems like Ubuntu LTS is unlikely to be affected a lot due to the older coreutils.
