2.6.35-longterm review patch. If anyone has any objections, please let me know.
------------------ From: Dan Carpenter <[email protected]> commit cb26a24ee9706473f31d34cc259f4dcf45cd0644 upstream. info->num comes from the user. It's type int. If the user passes in a negative value that would cause memory corruption.
