Slackware 15.0: SSA:2025-192-01 critical: kernel security upgrade

Installation instructions: Upgrade the packages as root: # upgradepkg kernel-*.txz If you are using an initrd, you'll need to rebuild it. For a 32-bit SMP machine, use this command (substitute the appropriate kernel version if you are not running Slackware 15.0): # /usr/share/mkinitrd/mkinitrd_command_generator.sh -k 5.15.187-smp | bash For a 64-bit machine, or a 32-bit uniprocessor machine, use this command (substitute the appropriate kernel version if you are not running Slackware 15.0): # /usr/share/mkinitrd/mkinitrd_command_generator.sh -k 5.15.187 | bash Please note that "uniprocessor" has to do with the kernel you are running, not with the CPU. Most systems should run the SMP kernel (if they can) regardless of the number of cores the CPU has. If you aren't sure which kernel you are running, run "uname -a". If you see SMP there, you are running the SMP kernel and should use the 5.15.187-smp version when running mkinitrd_command_generator. Note that this is only for 32-bit -- 64-bit systems should always use 5.15.187 as the version. If you are using lilo or elilo to boot the machine, you'll need to ensure that the machine is properly prepared before rebooting. If using LILO: By default, lilo.conf contains an image= line that references a symlink that always points to the correct kernel. No editing should be required unless your machine uses a custom lilo.conf. If that is the case, be sure that the image= line references the correct kernel file. Either way, you'll need to run "lilo" as root to reinstall the boot loader. If using elilo: Ensure that the /boot/vmlinuz symlink is pointing to the kernel you wish to use, and then run eliloconfig to update the EFI System Partition.
