The function to prepare MEX type 50 ap messages did not explicitly check for the data length in case of data > 512 bytes. Instead the function assumes the boundary check done in the ioctl function will always reject requests with invalid data length values. However, screening just the function code may give the illusion, that there may be a gap which could be exploited by userspace for buffer overwrite attacks.

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.
