+Subject: [PATCH] loader/xnu: Fix memory leak
+
+The code here is finished with the memory stored in name, but it only
+frees it if there curvalue is valid, while it could actually free it
+regardless.
+
+The fix is a simple relocation of the grub_free() to before the test
+of curvalue.
+
+Fixes: CID 96646
