When attempting to use the Security Advisor GUI to install KernelCare, the page simply refreshes upon attempt without applying the free Symlink Protection patch.
Kernels that are not supported by KernelCare will still receive a Security Advisor recommendation to install KernelCare and apply the free patch for Symlink Protection.
Security Advisor shouldn't be recommending the installation as the kernel is not supported by KernelCare.
We've opened an internal case for our development team to investigate this further. For reference, the case number is CPANEL-38990. Follow this article to receive an email notification when a solution is published in the product.
Ensure the server is running a kernel that is supported by KernelCare. You may obtain the kernel version via:
# uname -r
And visit https://patches.kernelcare.com/ to verify your server's kernel has an available patch.
