Background
The Kernel package is a crucial component of the Linux operating system. It provides the core functionality and acts as an interface between the hardware and software layers. The mtd (Memory Technology Devices) subsystem within the Kernel is responsible for managing flash memory devices. The qcom parser module within the mtd subsystem is specifically designed for Qualcomm devices. This vulnerability affects the qcom parser module and can potentially lead to memory leaks and resource exhaustion if not addressed.
Vulnerability Detail
