Subject: sctp: fix overrun in sctp_diag_dump_one()
From: Lance Richardson <lrichard@xxxxxxxxxx>
[ Upstream commit 232cb53a45965f8789fbf0a9a1962f8c67ab1a3c ]
The function sctp_diag_dump_one() currently performs a memcpy()
of 64 bytes from a 16 byte field into another 16 byte field. Fix
by using correct size, use sizeof to obtain correct size instead
of using a hard-coded constant.
