From: Dave Kleikamp Subject: [PATCH] sparc/crypto: initialize blkcipher.ivsize Date: Mon, 5 Oct 2015 10:08:51 -0500 Message-ID: <56129283.1090804@oracle.com> Mime-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Cc: linux-crypto@vger.kernel.org, sparclinux@vger.kernel.org, LKML To: "David S. Miller" Return-path: Sender: sparclinux-owner@vger.kernel.org List-Id: linux-crypto.vger.kernel.org Some of the crypto algorithms write to the initialization vector, but no space has been allocated for it. This clobbers adjacent memory.
