I’ve seen many systems go down over the last few days worldwide. Aside from the possibility of a mega-DDoS attack (which Facebook denies), all of these organizations have fairly diverse tech stacks to my knowledge. Google’s issue (supposedly) had to do with their Blobstore API, we don’t know what happened with Facebook, and many other, smaller services have had issues as well, including three intranet services at my workplace.
This leaves me wondering what software all these places have in common. The application layers are all different, the databases are all different, the containerization and provisioning systems are different, but I imagine that all these systems rely on two things: the global Internet backbone, and maybe the Linux kernel.
Have there been major security vulnerabilities patched lately in the Linux kernel that could have had unintended consequences?
