On May 1st, a new vulnerability CVE-2018-1000199, which can lead to corruption and DoS,  was disclosed for Linux kernel. The error reported has illustrated exploits for x86 kernels, but other kernels can be affected as well.

According to Andy Lutomirski, who discovered the vulnerability, “the bug itself is spread all over the place in the kernel in generic and arch code”.

“Our dedicated team of kernel developers work around the clock to deliver patches that fix vulnerability issues without customers needing to reboot servers,” – said Igor Seletskiy, CloudLinux CEO. “We are the only vendor supporting live patching for many distributions that has rolled out patches to fix some of the most critical vulnerabilities, such as Meltdown, and we are very proud of the Kernel experts we have on our team”.

Companies like Dell, Endurance, and LiquidWeb have been protecting their kernels against security vulnerabilities, such as Meltdown and Spectre, without reboots. Their kernels have been patched without costly and inconvenient application downtime. KernelCare delivers virtually no performance impact during updates. Launched four years ago, it supports most popular Linux distributions including CentOS and RHEL, Xen4CentOS, OpenVZ & Virtuozzo, Debian and Ubuntu.
