It’s been released some days ago but here are the download links and a way to install the kernel. Use on your own risk stuff like wifi and vga drivers may not work.
Before you can install the kernel you need to download them first you can download the kernels from here:
For 32 bit systems:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6.2-quantal/linux-headers-3.6.2-030602_3.6.2-030602.201210121823_all.deb
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6.2-quantal/linux-headers-3.6.2-030602-generic_3.6.2-030602.201210121823_i386.deb
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6.2-quantal/linux-image-3.6.2-030602-generic_3.6.2-030602.201210121823_i386.deb
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6.2-quantal/linux-image-extra-3.6.2-030602-generic_3.6.2-030602.201210121823_i386.deb
To install the kernel open a terminal window (press Ctrl+Alt+T) and copy+paste the following lines:
cd ~/Downloads/
sudo dpkg -i linux-headers-3.6.2-030602_3.6.2-030602.201210121823_all.deb linux-headers-3.6.2-030602-generic_3.6.2-030602.201210121823_i386.deb linux-image-3.6.2-030602-generic_3.6.2-030602.201210121823_i386.deb linux-image-extra-3.6.2-030602-generic_3.6.2-030602.201210121823_i386.deb
For 64 bit systems:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6.2-quantal/linux-headers-3.6.2-030602_3.6.2-030602.201210121823_all.deb

To install the kernel open a terminal window (press Ctrl+Alt+T) and copy+paste the following lines:
cd ~/Downloads/
sudo dpkg -i linux-headers-3.6.2-030602_3.6.2-030602.201210121823_all.deb linux-headers-3.6.2-030602-generic_3.6.2-030602.201210121823_amd64.deb linux-image-3.6.2-030602-generic_3.6.2-030602.201210121823_amd64.deb linux-image-extra-3.6.2-030602-generic_3.6.2-030602.201210121823_amd64.deb
When the kernel is installed you can close your terminal window and reboot your system to use the newly installed kernel.
