commit8c1d6a050aupstream. Commitf3cc6b25dc("ima: always measure and audit files in policy") lets measurement or audit happen even if the file digest cannot be calculated. As a result, iint->ima_hash could have been allocated despite ima_collect_measurement() returning an error. Since ima_hash belongs to a temporary inode metadata structure, declared at the beginning of __ima_inode_hash(), just add a kfree() call if ima_collect_measurement() returns an error different from -ENOMEM (in that case, ima_hash should not have been 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.
