Background
The Kernel is a critical component of the Linux operating system that manages system resources and facilitates communication between hardware and software. It provides essential functions for device drivers, memory management, and process scheduling. The USB subsystem in the Kernel enables the use of USB devices and handles their communication. However, a vulnerability has been discovered in the 'max-3421' USB driver, which can lead to the corruption of freed memory.
Vulnerability Detail
The vulnerability in the 'max-3421' USB driver arises from a flaw in memory management. When certain operations are performed on USB devices, the driver fails to properly handle the freeing of memory, resulting in potential memory corruption. An attacker could potentially exploit this vulnerability to execute arbitrary code or cause a denial-of-service condition. The impact and attack plausibility of this vulnerability have not been proven yet. The vulnerability was introduced in version v3.16 of the Kernel and has been fixed in version v5.13.6.
How To Fix
