CVE-2025-8653

Root code execution via unchecked stack copy

Published Aug 6, 2025 · Updated Aug 6, 2025

Stack-based buffer overflow in JKRadioService in Kenwood DMX958XR 1.0.0509.3100 allows remote attackers to execute code over an adjacent network. JKRadioService copies attacker-controlled data into a fixed-length stack buffer without validating its length, allowing oversized input to overwrite stack memory. No authentication or user interaction is required, and successful exploitation runs code as root on the receiver.
