Therefore, fix the out-of-bounds read in \u0060v3d_csd_job_run()\u0060 by accessing only seven positions on the \u0027__u32 [7]\u0027 array. The eighth register exists indeed on V3D 7.1, but it isn\u0027t currently used. That being so, let\u0027s guarantee that it remains unused and add a note that it could be set in a future patch.",
