CVE-2018-5390

Priority
High
Description
Linux kernel versions 4.9+ 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.
Ubuntu-Description
Juha-Matti Tilli discovered that the TCP implementation in the Linux kernel
performed algorithmically expensive operations in some situations when
handling incoming packets. A remote attacker could use this to cause a
denial of service.
