No network or remote input reaches this path.\nAC:L - Within an affected resource-pool configuration the negative index is taken deterministically on every stream-add whose pipe_idx exceeds timing_generator_count; there is no race to win and no memory-layout condition the attacker must guess, and the attacker chooses when to issue the modeset.\nPR:L - A local unprivileged user with a DRM fd holding master — the ordinary case for a logged-in console/graphical session, an Android compositor client, or a kiosk display stack — can issue the atomic modeset; no capability check exists anywhere on the path from the ioctl to acquire_otg_master_pipe_for_stream().\nUI:N - The attacker performs the modeset/stream-add entirely on their own; no action by another user or administrator is required.\nS:U - The corruption and its consequences stay inside the kernel's amdgpu display driver under the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The −1 index reads pointers outside the intended arrays and installs them as wrongly-typed objects, so subsequent accesses read struct fields (funcs, inst, dc_context contents) at mismatched offsets from adjacent kernel objects, exposing kernel pointers and enabling further disclosure through the type-confused reads.\nI:H - stream_res.opp — actually a struct dpp * — is written through (opp->mpcc_disconnect_pending[] stores and mpc_tree_params list manipulation corrupt the DPP object), and both stream_res.tg->funcs and stream_res.opp->funcs are read from offsets holding non-vtable data, including gamma-LUT bytes supplied by userspace, giving an indirect call through attacker-influenced memory and thus a control-flow hijack primitive.\nA:H - At minimum the wrongly-typed or NULL pointer is dereferenced and called through during pipe programming, producing an immediate kernel oops/panic in the display pipeline, repeatable at will by the local attacker."
