commit763dafc520upstream. Commit7561252892("audit: always check the netlink payload length in audit_receive_msg()") fixed a number of missing message length checks, but forgot to check the length of userspace generated audit records. The good news is that you need CAP_AUDIT_WRITE to submit userspace audit records, which is generally only given to trusted processes, so the impact should be limited.

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.
