CVE-2025-15608

TP-Link Archer Ax53 Firmware remote code execution

9.8 CRITICALEPSS 0.64%
  1. Published20 Mar 2026

Description

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.
