Here are the details from the Slackware 15.0 ChangeLog:
+--------------------------+
patches/packages/linux-5.15.27/*: Upgraded.
 These updates fix various bugs and security issues, including the recently
 announced 'Dirty Pipe' vulnerability which allows overwriting data in
 arbitrary read-only files (CVE-2022-0847).
 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.
