Here are the details from the Slackware 14.2 ChangeLog:
+--------------------------+
patches/packages/linux-4.4.190/*: Upgraded.
 These updates fix various bugs and a minor local denial-of-service security
 issue. They also change this option:
 FANOTIFY_ACCESS_PERMISSIONS n -> y
 This is needed by on-access virus scanning software.
 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:
 Fixed in 4.4.190:
 [link moved to references]
 (* Security fix *)
+--------------------------+");
