Subject: [Qemu-devel] [PATCH] pr-manager: Fix invalid g_free() crash bug
Date: Thu, 22 Aug 2019 15:38:46 +0200 [thread overview]
Message-ID: <20190822133846.10923-1-armbru@redhat.com> (raw)
pr_manager_worker() passes its @opaque argument to g_free(). Wrong;
it points to pr_manager_worker()'s automatic @data. Broken when
commit 2f3a7ab39be converted @data from heap- to stack-allocated. Fix
by deleting the g_free().
Fixes: 2f3a7ab39bec4ba8022dc4d42ea641165b004e3e
