When parsing multi-attr we count the objects and then allocate an array to hold the parsed objects. If an attr space has multiple multi-attr objects, however, if parsing the first array fails we'll leave the object count for the second even tho the second array was never allocated. This may cause crashes when freeing objects on error. Count attributes to a variable on the stack and only set the count in the object once the memory was allocated.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
