What is CVE-2025-15608?

CVE-2025-15608 is a high-severity memory corruption vulnerability in TP-Link Systems Inc. AX53 v1, published on 20 Mar 2026. It can only be exploited from the same machine or local network, with no action from the victim.

Official 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.
