[ Upstream commit 04a4af334b971814eedf4e4a413343ad3287d9a9 ] For nested and variable attributes, the expected length of an attribute is not known and marked by a negative number. This results in an OOB read when the expected length is later used to check if the attribute is all zeros. Fix this by using the actual length of the attribute rather than the expected length.

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.
