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 denial of service. No authentication, session, or pairing is required.
Risk Assessment
An unauthenticated attacker with network access to the UDP service can repeatedly crash the TDP daemon, disrupting device operation and availability. This can lead to persistent unavailability of the monitoring service.
Recommendation
Update the TP-Link Tapo C500 v2.0 firmware to the latest version provided by the vendor. Restrict network access to the TDP UDP service if possible.

Original NVD description (English source)
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.
