From: Artem Savkov Subject: [PATCH] X.509: Fix double free in x509_cert_parse(). Date: Thu, 11 Aug 2016 14:18:56 +0200 Message-ID: <1470917936-23904-1-git-send-email-asavkov@redhat.com> Cc: dhowells@redhat.com, linux-crypto@vger.kernel.org, linux-kernel@vger.kernel.org, Artem Savkov To: tadeusz.struk@intel.com Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: linux-crypto.vger.kernel.org Patch "crypto: KEYS: convert public key and digsig asym to the akcipher api" introduced double freeing of cert->pub->key. There is no need to free it in error_decode label as it is later freed in x509_free_certificate().
