Here are the details from the Slackware 14.2 ChangeLog:
+--------------------------+
patches/packages/linux-4.4.19/*: Upgraded.
 A flaw was found in the implementation of the Linux kernels handling of
 networking challenge ack where an attacker is able to determine the shared
 counter. This may allow an attacker located on different subnet to inject
 or take over a TCP connection between a server and client without having to
 be a traditional Man In the Middle (MITM) style attack.
 Be sure to upgrade your initrd after upgrading the kernel packages.
 If you use lilo to boot your machine, be sure lilo.conf points to the correct
 kernel and initrd and run lilo as root to update the bootloader.
 If you use elilo to boot your machine, you should run eliloconfig to copy the
 kernel and initrd to the EFI System Partition.

 (* Security fix *)
