AI Analysis
Technical Summary
CVE-2026-5605 describes a stack-based buffer overflow in Tenda CH22 firmware version 1.0.0.1. The flaw resides in the formWrlExtraSet function of the /goform/WrlExtraSet endpoint, where improper handling of the GO argument allows remote attackers to overflow the stack buffer. This vulnerability can be exploited without user interaction and requires low attack complexity and privileges. The CVSS 4.0 vector indicates high impact on confidentiality, integrity, and availability. No vendor advisory or patch information is currently available.
Potential Impact
Successful exploitation of this vulnerability can lead to remote code execution or denial of service on affected Tenda CH22 devices. The high CVSS score reflects significant potential impact on device security and network integrity. There is no indication that the vulnerability affects cloud services or that exploits are currently observed in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider limiting remote access to the affected device and monitor for unusual activity. Avoid exposing the vulnerable endpoint to untrusted networks. Follow up with Tenda for updates on patches or official mitigations.
