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 (CWE-121) in TP-Link AX53 v1, AX55 v4, and AX55 v4.6 results from improper input validation in the probe handling logic. Unvalidated input parameters can cause a stack-based buffer overflow, leading to a crash of the affected service. Under certain complex exploitation scenarios involving heap spraying, remote code execution may be achieved, allowing attackers to control the device. The CVSS 4.0 base score is 7.7, indicating high severity, with attack vector being adjacent network and requiring high attack complexity and privileges. No known exploits in the wild or patches are currently reported.

Potential Impact

Successful exploitation can cause repeated service crashes leading to denial of service. In specific cases, it may allow remote code execution, giving attackers control over the device. This poses a significant risk to 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 currently available. Until a patch is released, monitor vendor communications for updates and consider limiting exposure of affected devices to adjacent networks where possible.
