{"id":"CVE-2026-57486","state":"PUBLISHED","title":"pupnp: NULL pointer dereference in ixmlNode_compare crashes on non-namespaced attributes","description":"pupnp is an SDK for development of UPnP device and control point applications.

Non-namespaced attributes created by ixmlDocument_createAttribute legitimately leave those fields NULL. When ixmlElement_removeAttributeNode compares two distinct attribute objects with the same nodeName through find_condition_node, the pointer-identity shortcut does not apply and the comparison dereferences NULL, causing a process crash when application handling of attacker-controlled XML reaches this path.
