Hello AlmaLinux Users,

A few days ago Xint Code disclosed Copy Fail (CVE-2026-31431), a Linux kernel logic flaw in the crypto subsystem (algif_aead chained through AF_ALG and splice()). It lets any unprivileged local user escalate to root with a 732-byte exploit that the researchers report is 100% reliable across every mainstream Linux distribution built since 2017.

Every supported AlmaLinux release is affected. Red Hat has not yet shipped a kernel update, so our core team has built patched kernels for AlmaLinux 8, 9, 10, and Kitten 10 using the upstream fix. ALESCo approved shipping ahead of upstream - the patched kernels are in the testing repository today, and they'll move to production once the community has helped us verify them.

If you can spare a test box - especially anything multi-tenant, a container host, or a CI runner where untrusted users get a shell - we'd love your help testing. Full instructions, kernel versions, and feedback channels are on the blog:

Hi,

I'm using AlmaLinux as workstation and for some project (work project) I'm using it as base but reading how US is doing with foreign countries (like EU) I have some concerns about limitation or ban in EU countries like done with fedora for embargoed nations (https://fedoraproject.org/wiki/Embargoed\_nations).

Considering the latest interaction between USA and EU there is a way that AlmaLinux could be blocked or banned for EU?

I see many are migrating to more safe place like Ubuntu and Debian due to this "problem" like many countries are abandoning US Software/OS (mostly from MS Win but this could be applied to RHEL) for safe project like France going with Debian/Ubuntu distro/derivatives, Denmark with NixOS, in Germany they used Limux in the past and OpenSUSE.

So there is a real possiblity that this will happen?

AlmaLinux as an Indipendente OpenSource project base on CentOS Stream and this should not affect its diffusion but the headquarter is based in US so, technically they can be forced to adopt action if restriction will do.

So, I would ask to AlmaLinux Board: there is a way that US gov can block AlmaLinux to EU countries?

Thank you in advance

Hi everyone,

We're running an Omnissa Horizon infrastructure and have several AlmaLinux 9 clients in our environment. Unfortunately, AlmaLinux 9 is not officially supported by Omnissa, as listed in their compatibility matrix: 👉 https://kb.omnissa.com/s/article/87277?lang=en_US

We reached out to Omnissa support, but they told us it's on the AlmaLinux team's side to contact them and implement the necessary changes to ensure compatibility with the Omnissa agent software.

So here we are! 🙂 Is there any chance the AlmaLinux team — or anyone in the community — could look into this? Omnissa Horizon is widely used in enterprise environments, and having native support for AlmaLinux 9 would be a significant benefit for many organizations already using or considering AlmaLinux as their RHEL alternative.

Thanks in advance for any input or visibility on this!

Is alma what I'm looking for if I'm tired of Fedora after 16+ years with it on desktop?

[skip this story, I couldn't stop writing. Just goto: relavent]
First thing I do to any notebook *(mostly thinkpads) and pc I get is installing Fedora, and it started somwhere in middle school, so 2006-2009.
I'm not even power user, because I'm not interested in staying stuck in dependency hell when wifi drivers already works.
However I guess that I'm "power user enough to make something bad", things that would hurt me in future? I'm constantly doing them.
When with Fedora 39 I found out that only with KDE one of few unnessesery features of KDE connect works, and Gnome version wouldn't handle it I decided to remove whole Gnome and dnf install kde-blahblah (the full version)
2 Upgrades later I had problems with bluetooth, and touchscreen of my yoga thinkpad.
I just started "it can be fixed" procedure, after which no usb, no wifi, no internet, no touchscreen, not even a red clitty button - nothing to move coursor was working ecool]
The most funny things? Somehow I couldn't even run usb live linux, becouse my family photos are portected with CryptSetup ❤️ And some process detected that I don't have usb disk, that I had, boom rapair some tables. (fu & ur tables dude, just boot, you are live usb fedora ment to just open encrypted disk so I can copy photos and documets, what dracula what initdsaporsadsasd)
However sorry, for this excended story, I'm facing stupid problems like that all the time, because I'm stupid and not afraid to play with things and brake them. It would make me awesome if I only could learn from it ❤️

:relavent
Most of things that I broke on Fedora, were things that were working, and fixed some problems for me, BUT broke after upgrade. Fedora have like upgrade every year, or something like that? Alma is same family but it's like server version, similar to RHEL, so it's not filled with "cutting edge" packages I didn't ever needed.
Tell me I'm wrong/right and I would read your opinions. Install it anyway to try it out, and then come back to this thread.
