CVE-2026-9216: CWE-121 Stack-based buffer overflow in NETGEAR RAX30
An insufficient input validation vulnerability in the listed NETGEAR RAX series models allows a network-adjacent attacker having network access (such as WiFi credentials) to crash the router's management UI. There is no confidentiality or integrity impact. A crash of the router's management UI does not impact the availability of the router's core services like WiFi network.
AI Analysis
Technical Summary
This vulnerability (CWE-121) in NETGEAR RAX30 routers arises from insufficient input validation in the router's management UI. An attacker with network access can trigger a stack-based buffer overflow that causes the management UI to crash. The core router functions remain operational despite the UI crash. No confidentiality or integrity impacts are reported.
Potential Impact
The primary impact is limited to availability of the router's management UI, which can be crashed by an attacker with network access. There is no impact on the confidentiality or integrity of data, and the router's core services such as WiFi remain unaffected.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or workaround is currently documented. Until a patch is available, restrict network access to trusted users and monitor for attempts to crash the management UI.
