VulnerabilityCVE-2025-15608cvecve-2025-15608cwe-121
Published: 03/20/2026 (03/20/2026, 16:31:38 UTC)
Source: CVE Database V5
Vendor/Project: TP-Link Systems Inc.
Product: AX53 v1

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.

Technical Analysis

This vulnerability affects TP-Link AX53 v1, AX55 v4, and AX55 v4.6 routers due to improper input validation in the probe handling logic. Unvalidated input parameters can cause a stack-based buffer overflow, resulting in service crashes. Additionally, complex heap-spray techniques may be used to achieve remote code execution. The CVSS 4.0 base score is 7.7, indicating a high severity. No patch or official remediation is currently documented. The vulnerability is not known to be exploited in the wild.

Potential Impact

Successful exploitation can cause repeated service crashes leading to denial of service. In certain scenarios, attackers may gain remote code execution capabilities, potentially allowing full control over the affected device. This compromises device availability and security.

Mitigation Recommendations

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided at this time. Until a patch is available, affected devices should be monitored closely and network exposure minimized where possible.
