CVE-2025-15608

Service crash or code execution via probe overflow

Published Mar 20, 2026 · Updated Mar 20, 2026

Stack-based buffer overflow in tdpServer on TP-Link Archer AX53 v1 before 251029 allows remote attackers on an adjacent network to crash the service. The probe-handling logic copies unvalidated parameters into a fixed-size stack buffer without sufficient bounds enforcement. No authentication or user interaction is required, but code execution requires complex heap spraying; successful attacks repeatedly interrupt the service or take control of the device.
