OpenSSH 10.6p2 released

In an announcement posted on social media, Damien Miller ( djm@ ) writes,

OpenSSH 10.6p2 has been released with a workaround for a critical vulnerability.

If you operate a Linux system that uses musl libc without PAM (Alpine Linux is one example) then stop reading and set PasswordAuthentication=no or disable SSH for these systems IMMEDIATELY.

This vulnerability does not exist on non-Linux systems, Linux/glibc systems and Linux systems that use PAM for password authentication.

We consider the root cause of this bug to be outside OpenSSH itself, but we're in a good position to deliver a mitigation quickly.

Work on GEFS (the Good Enough File System) for OpenBSD progresses

As previously reported, Ori Bernstein is working on GEFS, the "Good Enough File System" imported to OpenBSD , and his EuroBSDCon 2026 presentation was very well received. In fact, the video is among the most frequently played from the conference.

Now Ori has followed up with more evolved code that includes several important steps towards makin the new file system fit for general use. In a message to tech@, Ori writes:

So, it's probably time for a few updates. First
off, thanks to Martijn, and everyone else who
tried it out and sent patches.

Everything is updated and rebased, and the diff
has been regenerated with all of the lastest.
