CVE-2025-15608
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThis vulnerability in AX53 v1, AX55 v4 and AX55 v4.6 results from insufficient input sanitization in the device’s probe handling logic, where unvalidated parameters can trigger a stack-based buffer overflow that causes the affected service to crash and, under specific conditions, may enable remote code execution through complex heap-spray techniques. Successful exploitation may result in repeated service unavailability and, in certain scenarios, allow an attacker to gain control of the device.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThis is a stack-based buffer overflow vulnerability in the probe handling logic of AX53 v1, AX55 v4, and AX55 v4.6 network devices. Insufficient input sanitization allows unvalidated parameters to overflow a stack buffer, causing repeated service crashes and potentially enabling remote code execution through complex heap-spray techniques.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify your device modelCheck the device label or web interface (typically at 192.168.0.1) to confirm the exact model number - look for AX53, AX55 v4, or AX55 v4.6Affected if Device is not one of these three models
-
Check the installed firmware versionAccess the router web interface, go to the firmware upgrade or status page, and record the firmware version. For AX53, verify if version equals 1.0Affected if AX53 firmware is exactly version 1.0, or AX55 is v4 or v4.6 regardless of minor version
-
Locate the probe handling serviceCheck router admin interface for any wireless probe response, Airtime Fairness, or beamforming settings - this vulnerability exists in the probe handling logicAffected if Probe-related features are enabled on the device
-
Verify network exposure of the probe serviceAssess whether the wireless management or admin interface is accessible from untrusted networks. Check if WAN access to port 80/443 on the router is permittedAffected if The router admin or wireless probe service is exposed to WAN or untrusted LAN segments
-
Check for service instability indicatorsReview system logs (typically under System Tools > System Log) for repeated wireless service restarts, crash reports, or abnormal error messages mentioning probe or wireless driver failuresAffected if Multiple wireless service restarts or crash logs are present in the system log
You are affected if you own an AX53 (firmware 1.0), AX55 v4, or AX55 v4.6 device AND have probe-related wireless features enabled AND the management interface is network-accessible.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor firmware updates when available; if no patch exists, restrict network access to the device's management interface and disable unnecessary probe services to reduce attack surface.
