Getting involved with the Promo SIG is so easy, @DeSheaWitcher85 and @bennyvasquez can explain how to do it in under a minute. ⏱️
👻 For years, @bennyvasquez has had strange things happen whenever she records.
No matter what she does, the glitches persist. Only one explanation remains: this is a haunting. 😱
AlmaLinux OS may be stable, but we can’t say the same for benny’s setup. Happy Halloween! 🎃
ICYMI, the patched PHP packages for CVE-2026-109618 and CVE-2026-109619 have been rolled out to the production repositories for every PHP stream on AlmaLinux 8, 9, and 10.

A Code of Conduct is not a firewall.
@bennyVasquez digs into what actually holds a community together at #SFSCon: “Your Code of Conduct is Killing Your Community (And What to Build Instead)”
We won't have a booth, but we will have cupcakes! 🧁 @SFScon
We're so grateful to everyone who has helped translate the AlmaLinux website, but the work is not yet done!
We're looking for help to bring AlmaLinux to more languages.

The real superpower of open source in science isn’t the code, it’s the people!

When major Linux kernel vulnerabilities are announced, Dr. @owainkenway of @ucl watches our team ship fixes in the open, in real time.
That transparency helped make AlmaLinux the choice for a major UCL system. youtube.com/watch?v=kgizIcwT… with @bennyvasquez
.@TuxCare_ contributed free DISA STIG automation for AlmaLinux OS 9 to the ComplianceAsCode project!
Point OpenSCAP at an AlmaLinux OS 9 system to get a report of which STIG requirements it meets, rather than working through a few hundred of them by hand. almalinux.org/blog/2026-10-2…
Open source works when people show up! 👏
@bennyvasquez and @DeSheaWitcher85 discuss how the Promo SIG benefits the broader AlmaLinux community.
📢 A new Linux kernel vulnerability, tracked by Trend Micro’s Zero Day Initiative (ZDI) as ZDI-CAN-33367, is the same kind of bug as Dirty Frag and Fragnesia.
AlmaLinux 8, 9, and 10 are affected. Patched kernels are available for testing!

PwnEscape (CVE-2026-99999): a guest VM can attack its host kernel to leak memory, crash it, or gain root. Rated Critical.
AlmaLinux 8, 9, and 10 are affected. Patched kernels are available now. almalinux.org/blog/2026-10-1…

Researcher finds it, kernel devs write an upstream fix, distros pick it up.
PwnEscape (CVE-2026-99999) is a KVM guest-to-host escape, and the open source loop is already running on it.

.@evanrkeller built a web app that tracks his pilot friends’ planes on a vertical touchscreen at their weekly airport meetup.
It runs on AlmaLinux, on a Dell and a Raspberry Pi. Hear how it came together: youtube.com/watch?v=VqWQfyd5… @kellersolution @bennyvasquez
Traditional HPC means SSH, shell scripts, and a batch queue.
@ucl's new AlmaLinux system keeps that, then adds JupyterHub, RStudio, MATLAB and Galaxy through a side cloud! youtu.be/kgizIcwTb60 with @owainkenway @bennyVasquez
Two critical vulnerabilities in PHP, nicknamed php2shell, were disclosed by PHP today: CVE-2026-109618 and CVE-2026-109619.
AlmaLinux 8, 9, and 10 all ship affected PHP versions, and we will release patched packages for testing today.

Patched PHP packages are now in testing!
