From: Kees Cook keescook@chromium.org Date: Fri, 5 May 2017 15:30:23 -0700 Subject: [PATCH] bna: ethtool: Avoid reading past end of buffer
Using memcpy() from a string that is shorter than the length copied means the destination buffer is being filled with arbitrary data from the kernel rodata segment. Instead, use strncpy() which will fill the trailing bytes with zeros.
This was found with the future CONFIG_FORTIFY_SOURCE feature.
