Dirty CoW kernel check - CentOS

So there's been a load of work due to the Dirty CoW vulnerability... you need to find out if there's been a kernel update so that you can reboot your CentOS P/VM... Here's a oneliner:

if [ "`rpm -q kernel --queryformat '%{installtime} %{version}-%{release}.%{arch}\n' | \
sort -n -k1 | tail -1 | cut -d ' ' -f 2`" = "`uname -r`" ]; \
then echo "You are running the latest kernel" && uname -r; \
else echo "There is a new kernel. You need a reboot" && echo "Current kernel: " && uname -r &&  \
echo "The latest kernel: " && rpm -q kernel --queryformat '%{version}-%{release}.%{arch}\n' | sort -n -k1 | tail -1;  fi

This is what it looks like on CentOS 6:

# if [ "`rpm -q kernel --queryformat '%{installtime} %{version}-%{release}.%{arch}\n' |sort -n -k1 | tail -1 | cut -d ' ' -f 2`" = "`uname -r`" ]; then echo "You are running the latest kernel" && uname -r; else echo "There is a new kernel. You need a reboot" && echo "Current kernel: " && uname -r && echo "The latest kernel: " && rpm -q kernel --queryformat '%{version}-%{release}.%{arch}\n' | sort -n -k1 | tail -1;  fi
There is a new kernel. You need a reboot
Current kernel:
2.6.32-642.4.2.el6.x86_64
The latest kernel:
2.6.32-642.6.2.el6.x86_64

The table below shows which kernel you should be running to fix the Dirty CoW vulnerability:

Distro	Kernel version
CentOS 5	2.6.32-642.3.1.el6.x86_64
CentOS 6	2.6.32-642.6.2.el6.x86_64
CentOS 7	3.10.0-327.36.3.el7.x86_64
Debian 7	3.2.82-1
Debian 8	3.16.36-1+deb8u2
