Executive Summary

This vulnerability is in the Linux kernel's drm/rockchip lvds driver, where the power management usage counter becomes unbalanced due to the function pm_runtime_get_sync incrementing the usage counter even when it fails. This leads to a reference leak. The issue was fixed by replacing pm_runtime_get_sync with pm_runtime_resume_and_get to ensure the usage counter remains balanced.

Impact Analysis

The unbalanced power management usage counter can cause a reference leak, potentially leading to improper power management behavior, resource leaks, or system instability in devices using the affected Linux kernel component.
