    I get following email

    Code:
    Current kernel version does not match the kernel version for boot. running kernel: 3.10.0-427.36.1.lve1.4.43.el7.x86_64, boot kernel: 3.10.0-427.36.1.lve1.4.39.el7.x86_64 Reboot the system in the "Graceful Server Reboot" area. Check the boot configuration in grub.conf if the new kernel is not loaded after a reboot.
    
    The mail says i am running latest kernel

    3.10.0-427.36.1.lve1.4.43.el7.x86_64

    But my boot kernel is

    3.10.0-427.36.1.lve1.4.39.el7.x86_64

    Look like there is some bug in this email as i am using latest kernel, still sent me this mail asking me to reboot.

    Hello,

    Please try to update kernel using below command and after that you have to verify the kernel installed on your system.

    Code:
     yum update 
    check kernel version.
    Code:
     uname -r

    I am not sure why this happen, maybe some of the cpanel cache problem. I did updated and rebooted, verified it is latest kernel.

    Even the the security warning email said i am running latest kernel

    Code:
    #  yum update 
    Loaded plugins: fastestmirror, rhnplugin
    This system is receiving updates from CLN.

    #  uname -r

    Hello,

    Could you let us know which version of cPanel is installed on the system, and if a grub2-efi.cfg file exists on the system? EX:

    Code:
    cat /usr/local/cpanel/version
    find /|grep grub2-efi.cfg
    Thank you.

    Here is the result

    Code:
    root@server20 [~]# cat /usr/local/cpanel/version
    11.62.0.17
    root@server20 [~]# find /|grep grub2-efi.cfg
    find: ‘/usr/share/cagefs-skeleton/proc/sys/fs/binfmt_misc’: Too many levels of symbolic links
    /etc/grub2-efi.cfg
    root@server20 [~]# ls -l /etc | grep grub2
    lrwxrwxrwx    1 root  root      22 Nov 21 16:39 grub2.cfg -> ../boot/grub2/grub.cfg
    lrwxrwxrwx    1 root  root      31 Nov 21 16:39 grub2-efi.cfg -> ../boot/efi/EFI/centos/grub.cfg
    root@server20 [~]# cat /etc/grub2-efi.cfg
    cat: /etc/grub2-efi.cfg: No such file or directory
    root@server20 [~]#
    
    This is not just one server. I see this problem with multiple server. I just got similar message from another server, screen screenshot.

    It says server running newer kernal.

    Code:
    running kernel: 3.10.0-427.36.1.lve1.4.43.el7.x86_64
    boot kernel: 3.10.0-427.36.1.lve1.4.39.el7.x86_64

    Hello,

    This shows you are using an EFI system and thus the warning message you are receiving is a false positive. Internal case CPANEL-11651 will address an issue where Security Advisor is unable to properly detect the boot kernel on an EFI-based system. The resolution is scheduled for inclusion with cPanel version 66.

    Thank you.
