Subject: netfilter: ipset: small potential read beyond the end of buffer
From: Dan Carpenter <[email protected]>
commit 2196937e12b1b4ba139806d132647e1651d655df upstream.
We could be reading 8 bytes into a 4 byte buffer here. It seems
harmless but adding a check is the right thing to do and it silences a
static checker warning.
