What is CVE-2022-24353?

This vulnerability affects TP-Link AC1750 routers, specifically the NetUSB.ko module, allowing network-adjacent attackers to execute arbitrary code on devices running affected firmware versions without requiring authentication. The flaw arises from inadequate validation of user-supplied data, potentially resulting in a read beyond the end of an allocated buffer. Successful exploitation could enable attackers to execute code with root user privileges, compromising the integrity of the affected device.
