Linux kernel bug: TCP flaw lets remote attackers stall devices with tiny DoS attack

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 lists a number of network-equipment vendors, PC and server manufacturers, mobile vendors, and operating-system makers that may be affected. Given the widespread use of Linux, the bug could affect every vendor from Amazon and Apple through to Ubuntu and ZyXEL.
