CVE-2026-3088: CWE-787 Out-of-bounds write in NETGEAR RBR860
Unauthenticated users on the local network can cause the router to become unavailable by sending specially crafted requests.
AI Analysis
Technical Summary
This vulnerability in the NETGEAR RBR860 router allows unauthenticated local network users to trigger an out-of-bounds write condition by sending specially crafted requests. This can cause the device to become unavailable, effectively a denial of service. The CVSS 4.9 score reflects medium severity with no privileges or user interaction required, but local network access is necessary. There is no vendor advisory or patch available at this time, and no known exploits in the wild have been reported.
Potential Impact
Successful exploitation results in denial of service by making the router unavailable. This disrupts network connectivity for users relying on the affected device. No information indicates further compromise such as code execution or data leakage.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict local network access to trusted users and monitor for unusual activity. No official mitigation or temporary fix has been published by NETGEAR.
