+Subject: [PATCH] Small memory leak fix (CVE-2019-6502 in #1586)
+
+CVE-2019-6502 was assigned to what appears to be a very minor
+memory leak that only occurs on an error-case in a CLI tool.
+If util_connect_card fails, we still need to release the sc
+context previously allocated by sc_context_create else memory
+will leak.
