# CVE-2026-58016

> 7.5 HIGH

## Beschreibung

A flaw was found in GLib. A state confusion issue exists in g_dbus_node_info_new_for_xml() in the gio/gdbusintrospection.c file when processing malformed D-Bus introspection XML, specifically with a `node` element nested within other elements like `method`, `signal`, `property` or `arg`. This issue can cause an unsigned integer overflow and lead to an out-of-bounds read, resulting in a denial of service.
