A flaw was found in libyang. This heap use-after-free write vulnerability, specifically within the lyd_parser_set_data_flags function, occurs when the software incorrectly updates metadata list pointers during the freeing of non-head default metadata entries. A remote attacker can exploit this by submitting specially crafted YANG XML documents containing specific metadata attributes to applications that parse untrusted XML data. Successful exploitation could lead to application process to crash.
