The global problem experienced in Windows systems due to the previous CrowdStrike severely disrupted operations in many sectors, including airlines, banks and healthcare providers. The issue was caused by a problematic file delivered via an update from cybersecurity service provider CrowdStrike. This crash did not affect computers using Mac or Linux operating systems.
While this latest incident attracted the attention of the whole world, it turned out that similar problems had been occurring for months, remaining in the background. Accordingly, in recent months, Debian and Rocky Linux users have also experienced significant outages as a result of CrowdStrike updates, raising serious concerns about the company’s software update and testing procedures. These events raised concerns about potential risks among customers who rely on the company’s products.
In April, a CrowdStrike update caused all Debian Linux servers at the civic tech lab to crash simultaneously and refuse to boot. It turns out that the update is incompatible with the latest stable release of Debian, despite the specific Linux configuration being supported. The lab’s IT team discovered that removing CrowdStrike allowed the machines to reboot and reported the incident.
In another incident, CrowdStrike users reported similar issues after upgrading to RockyLinux 9.4, causing their servers to crash due to a kernel bug. CrowdStrike support acknowledged the issue, highlighting the inadequate testing model and lack of attention to compatibility issues across different operating systems.
To avoid such issues in the future, CrowdStrike is required to prioritize rigorous testing on all supported configurations, and companies are required to approach CrowdStrike updates with caution and make contingency plans.
