The full story
A stack-based buffer overflow exists Vulnerability Tracked as CVE-2026-85384. A stack-based buffer overflow vulnerability exists in the httpd component of RE210 AC750 due to improper bounds checking in the splitString function when processing an uploaded configuration file. An authenticated attacker on the local network can upload a crafted configuration file to trigger the overflow, leading to remote code execution.
The flaw is described as a buffer overflow vulnerability. A buffer overflow occurs when software writes more data into a memory area than it can safely hold. Successful exploitation could let an attacker run code on a vulnerable system, which can lead to broader compromise depending on the privileges of the affected service.

What this means
Risk depends on whether the affected technology and the affected component are deployed and reachable, because the reported flaw can lead to remote code execution. Exposure, privilege, business criticality and compensating controls should determine remediation priority.
What security teams should check now
- Inventory the affected product deployments and confirm whether the affected component and vulnerable release are present.
- Apply the vendor patch or mitigation for CVE-2026-85384 and validate the affected path after remediation.
What is not yet confirmed
- Available reporting does not currently indicate exploitation, but that can change as vendor, government or threat-intelligence reporting develops.
