You can download boot images of the firmware here: http://www.crucial.com/usa/en/support-ssd-firmware
Being boot images, they are OS independant.

The iso image is actualy Linux + a tool from jMicron + the firmware files. That means if you're already using Linux you should be able to extract the firmware files and flash them directly! All of this is untested (as I don't have my SSD yet) but heres a howto:
mkdir mnt sudo mount -o loop /path/to/the/iso mnt mkdir tmp cd tmp gunzip -c ../mnt/boot/core.gz | cpio -i
sudo /path/to/msecli -U -i opt/firmware -n /dev/sdX -rWARNING: Exchange /dev/sdX with the actual device!

Download the Crucial firmware updater at targetbsp suggested. Then run isohybrid on the .iso file which will make the ISO file usable for a CD or an USB drive. You should be able to "dd" the .iso to a USB drive. isohybrid can be found in the syslinux-tools package on Debian and it's derivatives. I've been using this method for years to update Crucial SSD firmware.
V10lator, Thanks for the info.
