Description
In the Linux kernel, the following vulnerability has been resolved: drm/msm/mdp5: Don't leak some plane state Apparently no one noticed that mdp5 plane states leak like a sieve ever since we introduced plane_state->commit refcount a few years ago in 21a01abbe32a ("drm/atomic: Fix freeing connector/plane state too early by tracking commits, v3.") Fix it by using the right helpers. Patchwork: https://patchwork.freedesktop.org/patch/551236/

Executive Summary

This vulnerability in the Linux kernel involves the drm/msm/mdp5 component where plane states were leaking due to improper handling of the commit reference count. Specifically, since the introduction of plane_state->commit refcount, the plane states were not being properly freed, causing a leak. The issue was fixed by using the correct helper functions to manage these states.

Impact Analysis

The vulnerability causes a leak of plane state objects in the Linux kernel's drm/msm/mdp5 component. This could potentially lead to increased memory usage or resource exhaustion over time, which might degrade system performance or stability.
