Summary
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/
