CVE-2025-15608: Buffer Overflow in Network Probe Handling Function of TP-Link Archer AX53 + Archer AX55
This 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.
Security readout for executives and security teams
Plain-English summary
A flaw in network probe processing can crash affected TP-Link Archer routers and may allow device takeover under difficult conditions. The reported scope covers Archer AX53 v1, AX55 v4, and AX55 v4.6 hardware, but the source bundle does not clearly identify vulnerable or fixed firmware versions.
Executive priority
Treat as a high-priority network-edge remediation, especially where untrusted users share wireless access. Establish the affected inventory promptly, verify TP-Link's current firmware guidance, and reduce adjacent-network reachability. Emergency incident status is not justified solely by this bundle because active exploitation is unconfirmed and code execution is described as difficult.
Technical view
Insufficient parameter validation in probe-handling logic can trigger a stack-based buffer overflow (CWE-121). Exploitation requires adjacent-network access and high complexity, with no privileges or user interaction. Crashes are the clearest reported outcome; code execution may be possible using complex heap-spray techniques. CVSS 4.0 is 7.7.
Likely exposure
Prioritize deployed AX53 v1, AX55 v4, and AX55 v4.6 devices reachable from untrusted adjacent networks, including poorly isolated wireless clients. Internet exposure is not established by the supplied CVSS vector. Exact affected firmware boundaries remain unclear because the supplied version records are internally ambiguous.
Exploitation context
The supplied sources do not establish active exploitation, and the CVE is not listed as KEV in the bundle. Exploitation is described as adjacent-network and high-complexity. Repeated service disruption appears more practical than code execution, which reportedly requires specific conditions and complex heap-spray techniques.
Researcher notes
The bundle identifies three hardware revisions but records version "0" with default status "unaffected," leaving firmware applicability uncertain. Do not infer broader model coverage or fixed builds. The CVSS vector indicates adjacent access and high complexity. Validate version boundaries directly against TP-Link guidance without attempting destructive reproduction on production equipment.
Mitigation direction
Inventory the listed router models, hardware revisions, regions, and installed firmware versions.
Review TP-Link FAQ 5025 and the exact model-specific firmware page for current remediation guidance.
Install only firmware TP-Link identifies for the device's exact hardware revision and region.
Restrict untrusted wireless or adjacent-network access until vendor guidance is applied.
Replace affected devices if supported corrective firmware is unavailable.
Validation and detection
Confirm each device's model, hardware revision, region, and installed firmware through trusted administration interfaces.
Compare installed firmware against TP-Link's advisory and matching regional firmware page.
Verify the approved firmware update completed and persisted after reboot.
Review monitoring for unexplained service crashes, restarts, or repeated availability loss.
Confirm guest and untrusted clients cannot reach router management or sensitive network segments.
