If you’re not familiar with KernelCare, it’s a commercial kernel live patching technology developed and provided by CloudLinux of its CloudLinux OS users. We’ve discussed CloudLinux’s KernelCare in a previous report if you’re curious to test drive it. However, today we’d like to inform those of you using CloudLinux 7 that a patch is now available for you if you’re using KernelCare, and it looks like it addresses the recently discovered race condition in Linux kernel’s af_packet implementation. The security flaw, however, does not affect CloudLinux 5 and 6.
