This KB: Kernel panic observed after booting 5.14.0-427.13.1.el9_4.x86_64 by falcon-sensor process. - Red Hat Customer Portal Thx Ian reporting this here. I tried the solution. First I rebooted with the previous kernel (9.3) and then I switched to the kernel backend: /opt/CrowdStrike/falconctl -s --backend=kernel I can confirm it works after rebooting to the latest kernel (and it’s a better solution than to uninstall).

switching Crowdstrike to kernel backend means you can leave it enabled.
