CVE-2026-104944: Unauthenticated TDP Function Pointer Dispatch Denial of Service in TP-Link Tapo C500
TP-Link Tapo C500 v2.0 contains an out-of-bounds function-pointer dispatch in its TDP (TP-Link Device Protocol) daemon. A single unauthenticated UDP datagram can cause an invalid indirect call, crashing the main service and resulting in a denial-of-service condition.
Successful exploitation may allow an unauthenticated attacker with network access to the affected UDP service to repeatedly crash the TDP daemon, disrupting normal device operation and availability. No authentication, session establishment, or pairing is required to trigger the condition.

Frequently Asked Questions
Who can exploit this issue?
An unauthenticated attacker who has network access to the affected UDP service can trigger it. No account, session, or device pairing is required.
What does an attacker need to send?
A single UDP datagram to the affected TDP service is sufficient to cause the invalid indirect call and crash the TDP daemon.
What is the practical impact of exploitation?
Exploitation crashes the main TDP service, disrupting normal device operation and availability. An attacker may repeatedly send packets to repeatedly crash the daemon.
