Hallyn" , Roberto Sassu , linux-integrity@vger.kernel.org, linux-security-module@vger.kernel.org Cc: kernel-janitors@vger.kernel.org, linux-kernel@vger.kernel.org From: Colin Ian King An incorrect sizeof is being used, sizeof(*fields) is not correct, it should be sizeof(**fields). This is not causing a problem since the size of these is the same. Fix this in the kmalloc_array and memcpy calls.
