    Security researchers are warning Linux system users of a bug in the Linux kernel version 4.9 and up that could be used to hit systems with a denial-of-service attack on networking kit. The warning comes from Carnegie Mellon University's CERT/CC, which notes that newer versions of the Linux kernel can be "forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service (DoS)".
