Your link refers to secure boot. This issue is not related to the issue of bricking a samsung laptop UEFI firmware.
There is a fix for the linux kernel, but I don't know if the patch is availible for ubuntu 12.10.
I have read it is a Samsung problem, not Ubuntu problem

Protection against Samsung UEFI bug merged into Linux kernel
Since these patches have not yet been integrated into the installation media for these distributions, users should always use the UEFI firmware's Compatibility Support Module (CSM), which emulates a BIOS mode, when booting on affected laptops.
