From cce1a0d88445a62a2a92126af47cb81b377f656f Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Sat, 30 Jan 2016 17:38:28 +0300 Subject: crypto: keywrap - memzero the correct memory We're clearing the wrong memory. The memory corruption is likely harmless because we weren't going to use that stack memory again but not zeroing is a potential information leak.
