Fixing Dirty COW without rebooting servers

You may remember of HeartBleed?
It was really strange that OpenSSL has this bug.
Now we have similar thing with Linux Kernel.
It’s called Diry COW – CVE-2016-5195 and you can find more information about it here

Now, do you remember when I wrote article about CloudLinux & KernelCare ?
If you are like me, you won’t like restarting server every time kernel security patch is released.
That’s why we have KernelCare, you can try it for free (30 Days)!
