Thread-topic: [BUG] Resource leaks in Xen

Dear maintainers for Xen Project,

I am writing you to report potential resource leak bugs. In the file /xen/tools/flask/utils/label-pci.c, the methods fopen and fclose may not matched when returning at Line 76, resulting in a resource leak. Looking forward to your feedback. Thank for checking.

Locations, https://github.com/xen-project/xen/blame/25849c8b16f2a5b7fcd0a823e80a5f1b590291f9/tools/flask/utils/label-pci.c#L63-L76

Best,

Ryan Cai
