CyberVault Technical Summary

Analyst Synthesis

Technical analysis, exploit verification, and patch instructions for CVE-2025-15608 impacting tp-link archer_ax53_firmware. Evaluated with CVSS Base Score of 9.8 (CRITICAL).

Original NVD Description

Source: NIST NVD
This vulnerability in AX53 v1, AX55 v4 and AX55 v4.6 results from insufficient input sanitization in the deviceโ€™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.
