CrowdStrike recently caused a widespread Blue Screen of Death (BSOD) issue on Windows PCs, disrupting various sectors. However, this was not an isolated incident, CrowdStrike affected Linux PCs also.

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.

    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.

        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.

      This is the best explanation of this I’ve heard and you’re just like… A dude on Lemmy.
