If the sensor was using eBPF (as any modern sensor on Linux should) then the faulty update would have made the sensor crash, but the system would still be stable. But CrowdStrike has a long history of using stupid forms of integration, so I wouldn't put it past them to also load a kernel module that fucks things up unless it's blacklisted in the bootloader. Fortunately that kind of recovery is, if not routine, at least well documented and standardized.
I did hear that one of their newer versions does use eBPF, but I haven't even remotely looked into it.

They do have a bpf sensor. It's still shite, managing to periodically peg a CPU core on an idle system. They just lifted and shifted their legacy code into the bpf sensor, they don't actually make good use of eBPF capabilities.
