3.11.10.1 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Seppanen <eric@xxxxxxxxxxxxxxx>
commit 369653e4fb511928511b0ce81f41c812ff1f28b6 upstream.
extract_param() is called with max_length set to the total size of the
output buffer. It's not safe to allow a parameter length equal to the
buffer size as the terminating null would be written one byte past the
end of the output buffer.
