Description

In the Linux kernel, the following vulnerability has been resolved: drm/mipi-dsi: Detach devices when removing the host Whenever the MIPI-DSI host is unregistered, the code of mipi_dsi_host_unregister() loops over every device currently found on that bus and will unregister it. However, it doesn't detach it from the bus first, which leads to all kind of resource leaks if the host wants to perform some clean up whenever a device is detached.

Executive Summary

This vulnerability occurs in the Linux kernel's drm/mipi-dsi component. When the MIPI-DSI host is unregistered, the function mipi_dsi_host_unregister() unregisters all devices on that bus but fails to detach them first. This improper handling leads to resource leaks because the host cannot properly clean up resources associated with the devices that should have been detached.

Impact Analysis

The vulnerability can cause resource leaks in the system when devices on the MIPI-DSI bus are unregistered without being properly detached. This may lead to inefficient resource usage, potential system instability, or degraded performance due to unreleased resources.
