    During the last week I get this on the Security Advisor of two different CentOS 6.9 with WHM v68.0.21

    Code:
    The system kernel is at version “”, but is set to boot to version “2.6.32-696.16.1.el6.x86_64”.
    You must take one of the following actions to ensure the system is up-to-date:
    Wait a few days for KernelCare to publish a kernel patch.
    Reboot the system.
    Rebooting doesn't do anything.

    Both servers report this
    Code:
    #uname -r
    2.6.32-696.16.1.el6.x86_64
    #kcare-uname -r
    2.6.32-696.16.1.el6.x86_64
    
    Is this a bug?

    Hi,

    Can you share a screenshot of the security advisory here? We will need to see that page fully.

    No need.
    That shows the issue.

    Hello,

    Could you run the following commands and let us know the output?

    Code:
    kcarectl --version
    kcarectl --check
    /usr/local/cpanel/3rdparty/bin/perl -e 'use Cpanel::Kernel::Status; use Data::Dumper; my $kernel = Cpanel::Kernel::Status::kernel_status(); print Dumper \$kernel;'
    Thank you.

    Yes here is the output

    Code:
    # kcarectl --version
    2.14-2
    # kcarectl --check
    The latest patch is applied.
    # /usr/local/cpanel/3rdparty/bin/perl -e 'use Cpanel::Kernel::Status; use Data::Dumper; my $kernel = Cpanel::Kernel::Status::kernel_status(); print Dumper \$kernel;'
    $VAR1 = \{
                'has_kernelcare' => 1,
                'running_latest' => '',
                'boot_version' => '2.6.32-696.16.1.el6.x86_64',
                'running_version' => '',
                'reboot_required' => 1,
                'unpatched_version' => '2.6.32-696.16.1.el6.x86_64'
              };

    Hello,

    It looks like the running kernel isn't detected. Feel free to open a support ticket using the link in my signature so we can take a closer look to see what's happening.

    Thank you.

    I will. However this message appeared after a cPanel update in late November or early December. Both servers are in the Release channel.

    Same issue here. We installed the KernelCare free patch:

    Code:
    [ root@cp1 ~># kcarectl --version
    2.14-2
    
    [ root@cp1 ~># kcarectl --check
    The latest patch is applied.
    
    [ root@cp1 ~># /usr/local/cpanel/3rdparty/bin/perl -e 'use Cpanel::Kernel::Status; use Data::Dumper; my $kernel = Cpanel::Kernel::Status::kernel_status(); print Dumper \$kernel;'
    $VAR1 = \{
                'reboot_required' => 1,
                'unpatched_version' => '2.6.32-696.18.7.el6.x86_64',
                'running_version' => '',
                'has_kernelcare' => 1,
                'boot_version' => '2.6.32-696.18.7.el6.x86_64',
                'running_latest' => ''
              };
