In the Linux kernel, the following vulnerability has been resolved:
drm/vc4: kms: Add missing drmcrtccommit_put
Commit 9ec03d7f1ed3 ("drm/vc4: kms: Wait on previous FIFO users before a commit") introduced a global state for the HVS, with each FIFO storing the current CRTC commit so that we can properly synchronize commits.
However, the refcounting was off and we thus ended up leaking the drmcrtccommit structure every commit. Add a drmcrtccommit_put to prevent the leakage.
