Which kernels does the Kernel Team support?

The Kernel Team provides support (security updates etc) for the Ubuntu kernels on all currently active releases, we do not support any non-Ubuntu kernels. A full list of the currently active releases can be found on the Releases page. For Long Term Support (LTS) releases, starting with Ubuntu 12.04, the desktop kernels and server kernels both receive five years support, this is reflected in the Releases page.
