I am running CentOS 6.5 on top of Linux kernel 2.6.32-358.6.1.el6.x86_64
I got a warning from my vserver hoster that I need to upgrade to a Linux kernel > 3.15-rc5 because there is a security breach that would allow my server to be taken over.
I did a yumupgrade, but it wouldn't upgrade the kernel to a higher version than 2.6.32-358.6.1.el6.x86_64.
Currently I am confused about how to go on.
Could anybody tell me what is going on and how he would act in my position? Thank you!
