Name of the Vulnerable Software and Affected Versions
TL-WR841N version v14
Description
A NULL pointer dereference occurs in the UPnP service when processing SOAP state variable query requests. A specially crafted SOAP query can cause the process hosting the UPnP service to terminate unexpectedly or become unstable. This leads to a denial-of-service condition that impacts UPnP discovery, state queries, and related management functions until the process is restarted or the device is rebooted.
