Ubuntu 22.04 & RHEL 9 are the major distros impacted. Docker images built on ubuntu:latest will also be impacted. The latest releases of Alpine/Debian/AL2 are all not impacted, they use 1.1.x lineage.
Amazon Linux 2022 Preview (the upcoming successor to Amazon Linux 2) is also using OpenSSL 3. Had to shut down one host I have using that for an ongoing project until Amazon makes another RC package update.
That was, as it turns out, the only OpenSSL 3 host I'm presently dealing with.
>If you’re using version 1.1.1, this vulnerability doesn’t affect you, but there is a 1.1.1 update coming on Tuesday as well, version 1.1.1s, which you’re still going to need to update to anyway so you might as well schedule some time on Tuesday, too.
