CrowdStrike broke Debian and Rocky Linux months ago, but no one noticed
A widespread Blue Screen of Death (BSOD) issue on Windows PCs disrupted operations across various sectors, notably impacting airlines, banks, and healthcare providers. The issue was caused by a problematic channel file delivered via an update from the popular cybersecurity service provider, CrowdStrike. CrowdStrike confirmed that this crash did not impact Mac or Linux PCs.
It turns out that similar problems have been occurring for months without much awareness, despite the fact that many may view this as an isolated incident. Users of Debian and Rocky Linux also experienced significant disruptions as a result of CrowdStrike updates, raising serious concerns about the company's software update and testing procedures. These occurrences highlight potential risks for customers who rely on their products daily.

You might as well say you don't support Linux.
I wonder how this shit works on NixOS.
If I'm remembering right, RHEL is Crowdstrike's primary Linux target. And NixOS wouldn't even be a factor since it's basically just not enterprise grade.
That said, they need a serious revision of their QA processes.
RHEL, Ubuntu, & Debian cover the vast majority of enterprise installs I imagine, and provide a solid testing base for developers in the Linux business software space.
Maybe you add Gentoo, some post-CentOS clones/forks, or other more niche industry/workload specific distros, but how you do skip Debian?
Enterprises I imagine are using RHEL, Ubuntu, SUSE's SLES and Oracle Linux and probably not Debian. But that's a guess. Where can statistics and numbers be found ?
Largish enterprise heavily using Debian, just 1 data point here but we do exist.
Nice.
consultant for large enterprises in australia, and i literally can’t say i’ve ever seen anyone running anything other than RHEL and amazon linux (so… RHEL) in production… unless we’re talking not for profits, and then that’s been a bit of a mixed bag
In the enterprise realm it is typically SUSE and RHEL.
I'm not an expert in any sense.
But it was always my impression that Ubuntu and Debian were what you use on personal machines, while RHEL is the baseline standard for professional servers.
Is that not accurate? CrowdStrike's target customer seems to be the sort of company that would insist on using RHEL for the enterprise features.
That is not accurate.
The enterprise systems I see are only certified on RHEL and SUSE, debian is not even a contender. Obviously Americans typically choose Rhel and europe goes for SUSE.
Debian doesn sell enterprise support.
I've been using Linux professionally for 15 years. It's been Debian or Ubuntu almost everywhere I have been. Although that might be regional.

A lot of companies run Debian and Debian based distros, Google on their servers for a start
Canonical and Debian both target the professional server space. I've spent pretty much my entire career working on Debian-based distros.
Hell, the one company I worked for that I expected to use RHEL used Ubuntu for everything, so 🤷♂️.
This is accurate.
There is another reply that says “this is not accurate” that includes true information to back you up.
For infrastructure, RHEL is the gold standard for large companies with a budget. The RHEL customer-base probably overlaps almost completely with CrowdStrike.
RHEL imitators are popular with people that value cost savings more than the corporate backing ( beyond individual cases, this DOES NOT describe the enterprise space ).
Ubuntu is very popular with developers in companies of all sizes. Outside of maybe being the base for containers, this is not how “infrastructure” choices are made though.
Debian is popular with Linux enthusiasts and, where they have influence, businesses may use that. In enterprise environments, it is less likely this group is the one making the decisions. Again though, individual cases exist.
Hot take: maybe bossware is a fucking drain on society, and people should stop buying it.
It's sad how accurate this is.
After getting a referral from your cyber insurance rep right?
Well, if the executive leech class wants workers to have bossware, there's not all that much people can do about it. Can't just decide to not use it if your employer demands it
Worse, my employer doesn't care about this shit but our clients are demanding we have the bossware installed.
I didn't mean the average worker. I meant the "executive leech class," because downtime of this scale means lost profits, which is something they care deeply about.
They care about quarterly profits. Preventing fuckups of this scale requires long-term effort which is not profitable by itself, it only prevents possible future fuckups, and this is why proper QC etc. aren't done. Short term profits over everything else.
In that case, it's time for the average workers to sabotage the bossware. Let the leech class solve the problem they create.
Hospitals are effected by this too.
Why are sensitive or critical hospital systems loaded with bossware? That itself is a breach of medical safety regulations and medical privacy. If such bossware fails for whatever reason - even sabotage, it's on the leach class. Prosecute them for murder.
So?
The software is not the problem. Software breaks all the time. The problem is monocultures and centralization. Building entire industry ecosystems all around a single point of failure. This is the just-in-time manufacturing supply chain disruptions and fragility all over again.
Who knew, a diverse ecosystem was a strength, not a weakness.
The software is the problem if it's produced with a corporate mentality of "ship first, fix later".
Yep, at this point the "security" companies can do with imitating malware development practices.
Everyone got an MBA and failed to realize it was just corporate brainwashing.

There's a concept in this industry where you eat your own dog food.
Deploying these updates to your own people could have avoided this mess.
Oh but they did. Turns out that this is specifically caused by one driver expecting another to be installed, the other one being for another of their products. If you have the other product installed, it doesn't crash, so it didn't crash on their machines because they have all their products installed and apparently not a single element of their test matrix has the single most common configuration they service
Do you have a source for that? I'm intrigued. Their own blog post is only talking about a "logic error".
I heard a different rumor, that the driver file they pushed was all zeros. I'm inclined to believe that one.
They were talking about the Linux instance, not the windows one.
It's a very educated guess based on the following:
The crash is a null pointer dereference, which a linter ought to catch.
The crash does not happen if you have crowdstrike sensor installed, which is weird because crowdstrike sensor's job is not to prevent any crashes.
Hence the guess: the update the pushed tries accessing memory in sensor, but if it's not installed the pointer is null and that's Bye-Bye.
I see, thanks for the clarification. Sounds plausible.
This is the best explanation of this I've heard and you're just like... A dude on Lemmy.
The article implies that CrowdStrike issue impacted only Debian and Rocky 9.4. Debian I can see. But how did something impact Rocky but not RHEL itself or Alma or Oracle?
Is Rocky actually different from RHEL now? Their entire brand promise is that they are the same.
@lemmee_in I can't find any news about this. Just a statement in a forum and everyone basing subsequent articles on that. It appears to have been limited to a single company? Is there any support for this claim?
Based on the article, it seems like the issue only happens on a specific distro. Is it only Rocky or other Debians?
I wonder if other distros experience similar issues. Maybe linux based users don't even install CS at all and try to leave their OS as lean as possible.
Nobody breaks Rocky ok (spoken in a gruff, low, mumbling voice)
It also broke windows the other day…
😂
Believe me, people noticed that one.
