KernelCare by CloudLinux Fixes Meltdown and Spectre Vulnerabilities Without Reboots

Share Article

KernelCare now live patches Meltdown and Spectre which exploit critical vulnerabilities in modern processors. KernelCare is the only vendor that supports live patching for many distributions.

CloudLinux, the leading developer of the security technologies for cloud providers today announced that KernelCare, its live patching service, now fixes Meltdown and Spectre vulnerabilities -- that could cause a massive security breach -- without the need to reboot servers. It is the only live patching technology to offer rebootless fixes for CentOS, RHEL, CloudLinux, and others.

KernelCare is the live patching technology that delivers uninterrupted security updates of the kernel, without any interference or downtime for software running on the server. It fixes only the affected part, without rebooting or restarting the server. With these targeted updates, KernelCare can minimize the change and do it live on a running server.

“Because of the complexities and downtime associated with fixing these vulnerabilities, many cloud providers and enterprises have not yet updated their servers but the impact, especially in the hosting community, can be severe,” - said Igor Seletskiy, CloudLinux CEO. “All our customers have been challenged with this issue, and many have contacted us asking for a solution. Fixing it without bringing down servers along with hundreds and thousands of customers hosted on each server is a major accomplishment of our KernelCare team that worked on it.”

A dedicated team of kernel developers have been working around the clock to deliver the patches that would fix the Meltdown and Spectre issues without customers needing to reboot servers. Those fixes are meant to prevent programs from peaking inside the kernel’s memory to prevent from a massive security disaster and performance lags. Launched over 3 years ago with over 100,000 servers running it, KernelCare delivers live patches for Meltdown and Spectre vulnerabilities for the following distributions:

CentOS 7 and CentOS 7 Plus
RHEL 7
CloudLinux 7, hybrid
Proxmox VE3.10

Coming soon:
CentOS 6
RHEL 6
CloudLinux 6
Virtuozzo 6
Ubuntu
Debian
others
