Background
The Kernel is a critical component of the Linux operating system that manages the system's resources and facilitates communication between hardware and software. It provides essential functions and services to ensure the proper functioning of the system. The remoteproc subsystem within the Kernel enables the execution of remote processors on embedded systems. The qcom_q6v5_mss module is responsible for managing the Qualcomm Hexagon DSP on certain Qualcomm SoCs. 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 occur when allocating memory regions for the Qualcomm Hexagon DSP. If an attacker can trigger the allocation of memory regions repeatedly, it can lead to a depletion of system memory resources, potentially causing a denial-of-service condition. The impact and attack plausibility of this vulnerability have not been proven yet.
