CVE-2022-24352

Root code execution via NetUSB buffer over-read

Published Mar 28, 2023 · Updated Feb 19, 2025

Out-of-bounds read in TP-Link AC1750 firmware before 211210 allows remote attackers on the local network to execute code as root. The NetUSB.ko kernel module fails to validate user-supplied data before reading beyond the end of an allocated buffer. No authentication or user interaction is required, and successful exploitation grants complete control of the router.
