Unauthenticated TDP Function Pointer Dispatch Denial of Service in TP-Link Tapo C500

Published Oct 6, 2026 · Updated Oct 7, 2026 · Assigned by TPLink

Vendor: TP-Link Systems Product: Tapo C500 v2.0 Category: Network devices

Description

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.
