Hello,  there left over Linux kernels form previous updates, it keeps them by default so 
you have the option to revert back is you system becomes unstable after a kernel update, 
you can safely remove them...
This will remove ALL versions but the current: 
  sudo apt-get remove --purge $(dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed 
"s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d')
