The latest kernel v126.96.36.199 is available for users of Linux Mint 13 as it is for users of Ubuntu 12.04. So Linux Mint is not behind Ubuntu 12.04 by design.
The difference is the way how available updates are presented and offered to the users.
The Mint Updates separates available updates into 5 categories: (1), (2), (3), (4) and (5). The higher the number the higher the potential risk that installing an update may affect overall system stability. By default, the Mint updater will only present and offer updates beloging to categories (1), (2) and (3).
Kernel updates can be found in category (5). Therefore you will never see them and as a consequence never install them.
+ Launch the Mint Updater
+ Go to "Edit" => "Preferences"
+ Inside the dialgue box "Preferences", in the columns "Safe" and "Visible" tick all tick boxes for all 5 categories.
From now on the Mint Updater will display and offer the same updates as the Ubuntu updater and roundabout at the same time, including kernel updates.
