From 6e49412016f5f28ae36c3eaa5a36ec787b788951 Mon Sep 17 00:00:00 2001 From: Johannes Thumshirn Date: Thu, 25 Jan 2018 09:09:25 +0100 Subject: [PATCH] nvme: don't free uuid pointer before printing it Commit df351ef73789 ("nvme-fabrics: fix memory leak when parsing host ID option") fixed the leak of 'p' but in case uuid_parse() fails the memory is freed before the error print that is using it. Free it after printing eventual errors.
