CVE-2024-38268Network attack vector

Thread crash via out-of-bounds MAC parsing

Published Sep 24, 2024 · Updated Sep 24, 2024

Memory corruption in Zyxel VMG8825-T50K firmware 5.50(ABOM.8)C0 and earlier allows remote authenticated users to crash a device thread. The MAC address parser fails to restrict memory operations to buffer bounds while processing attacker-supplied address data, corrupting memory. Exploitation requires administrator privileges and network reachability; the reported consequence is a thread crash, not code execution or device takeover.
