CVE-2025-65553 identifies a vulnerability in the D3D Wi-Fi Home Security System ZX-G12 version 2.1.17 where the 433 MHz alarm sensor channel is susceptible to radio frequency jamming. This vulnerability allows an attacker within RF range to transmit continuous interference signals that block sensor communications. Because the device lacks any jamming detection or mitigation features, this interference leads to a denial-of-service condition, preventing alarms from triggering and compromising the security monitoring function of the system.

The vulnerability causes a denial-of-service condition by blocking sensor transmissions on the 433 MHz channel, resulting in missed alarms and loss of security monitoring. This may lead to undetected intrusions or failure to trigger safety alerts. There is no impact on confidentiality or integrity reported. The CVSS score of 6.5 (medium severity) reflects the high impact on availability with no required privileges or user interaction.

No patch or official fix is currently available for this vulnerability. Since the device lacks jamming detection or mitigation, users should be aware of the risk of RF jamming attacks causing denial of service. Monitoring for unusual RF interference in the environment and considering alternative or additional security measures may help reduce risk. Check with the vendor for any future updates or advisories regarding mitigation or fixes.
