Executive Summary

This vulnerability is a memory leak in the Linux kernel's Direct Rendering Manager (DRM) client code. Specifically, when a new display mode is set in drm_client_modeset_probe, the previous mode was not properly freed, causing a memory leak. The fix ensures that the old mode is freed when a new mode is set.

Impact Analysis

The memory leak can lead to increased memory usage over time, potentially causing system instability or degraded performance if the leak accumulates. This could affect systems running the affected Linux kernel DRM client code, especially those frequently changing display modes.
