Here are the details from the Slackware 14.2 ChangeLog:
+--------------------------+
patches/packages/linux-4.4.38/*: Upgraded.
 This kernel fixes a security issue with a race condition in
 net/packet/af_packet.c that can be exploited to gain kernel code execution
 from unprivileged processes.
 Thanks to Philip Pettersson for discovering the bug and providing a patch.
 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.
 For more information, see:

 (* Security fix *)
