+Subject: [PATCH] storage: Fix returning of locked objects from
+ 'virStoragePoolObjListSearch'
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+CVE-2023-3750
+
+'virStoragePoolObjListSearch' explicitly documents that it's returning
+a pointer to a locked and ref'd pool that maches the lookup function.
+
+This was not the case as in commit 0c4b391e2a9 (released in
+libvirt-8.3.0) the code was accidentally converted to use 'VIR_LOCK_GUARD'
+which auto-unlocked it when leaving the scope, even when the code was
+originally "leaking" the lock.
+
+Revert the corresponding conversion and add a comment that this function
+is intentionally leaking a locked object.
+
+Fixes: 0c4b391e2a9
+Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=2221851
