Defensive Computing blog has a nice article on how to manually update the flash plugin in Chrome browser.
Chrome uses its own pepper flash plugin, which is independent from Adobe flash, hence you never need to install adobe flash if your using Chrome browser.
Normally you can just go into the Chrome menu and select "Help > About" to check for updates, but sometimes even that doesn't have the immediately released flash security update.
To immediately check and push an update to chrome type chrome://components/ in the url bar. You will see the current flash version and a button to check for and install updates.
tl;dr
chrome://components/
Updating Flash in Chrome browser
