Background
The Kernel is a crucial component of the Linux operating system that manages communication between hardware and software. It provides essential functions and services to enable the proper functioning of the system. The remoteproc subsystem within the Kernel allows for the execution of code on remote processors. The qcom_q6v5_mss module is responsible for managing the Qualcomm Hexagon DSP on certain Qualcomm processors. This vulnerability specifically affects the q6v5_alloc_memory_region function within the qcom_q6v5_mss module.
Vulnerability Detail
The q6v5_alloc_memory_region function in the qcom_q6v5_mss module in the Kernel suffers from memory leaks. These leaks can occur when allocating memory regions, leading to a waste of system resources. An attacker could potentially exploit this vulnerability to exhaust available memory, resulting in a denial-of-service condition. The impact and attack plausibility of this vulnerability have not been proven yet.
