https://github.com/raspberrypi/linux/issues/1447 port_parameter_get() failed to account for the header (u32 id and u32 size) in the size before memcpying the response into the response buffer, so overrunning the provided buffer by 8 bytes. Account for those bytes, and also a belt-and-braces check to ensure we never copy more than *value_size bytes into value.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
