Summary
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.
