CVE-2026-58016 on Cyberus Linux 26.05

Aliases: CVE-2026-58016

Packages: glib

Status: Invalid

Advisory Information

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.

Comment:

Upstream states:

The gdbus tool is a developer utility and is not expected to be security hardened.

As such the “critical” assessment from the NVD does not apply whatever the accuracy is.
