Here are the details from the Slackware 14.2 ChangeLog:
+--------------------------+
patches/packages/linux-4.4.74/*: Upgraded.
 This kernel fixes two 'Stack Clash' vulnerabilities reported by Qualys.
 The first issue may allow attackers to execute arbitrary code with elevated
 privileges. Failed attack attempts will likely result in denial-of-service
 conditions. The second issue can be exploited to bypass certain security
 restrictions and perform unauthorized actions.
 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.
