Whether the machine contains an ASIC reporting more than six streams is entirely a property of the installed silicon and wholly outside any attacker's influence.\nPR:N - No capability check, credential test, or access-control gate exists anywhere on the path — `amdgpu_dm_initialize_drm_device()` runs unconditionally as part of the IP-block hardware init during device probe. On a system with qualifying hardware the out-of-bounds accesses occur automatically at boot before any account exists, so the attacker needs no privileges at all.\nUI:N - The amdgpu display manager initializes automatically when the PCI device is probed at boot; no victim must open a file, mount anything, or take any other action.\nS:U - The out-of-bounds read and write both stay inside kernel memory (`struct dc_caps` and `struct amdgpu_device`) and are handled entirely by the kernel's own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Reading `dc->caps.planes[i]` past index 5 pulls adjacent `struct dc_caps` bytes (`color`, `dmub_caps`, and following fields) and misinterprets them as a `struct dc_plane_cap`, from which `amdgpu_dm_plane_init()` derives the advertised pixel formats, DRM format modifiers, and upscale/downscale limits that any local user holding a DRM fd can read back via `DRM_IOCTL_MODE_GETPLANE` and the `IN_FORMATS` blob. The accompanying heap-pointer overwrite of `struct amdgpu_device` is memory corruption that can be leveraged for further disclosure.\nI:H - `initialize_plane()` writes a freshly kzalloc'd `struct drm_plane *` past the end of `mode_info->planes[6]`, corrupting the adjacent `afmt[9]` pointer array and DRM property pointers inside `struct amdgpu_device`; the subsequent `amdgpu_dm_crtc_init(dm, mode_info->planes[i], i)` reads those slots back out of bounds and passes type-confused pointers to `drm_crtc_init_with_planes()`. An out-of-bounds pointer write combined with type confusion is a control-flow-relevant corruption primitive.\nA:H - The pre-fix `ASSERT()` expands to `WARN_ON_ONCE()`, which panics outright on the many builds running `panic_on_warn=1`, and execution then continues into the out-of-bounds accesses that corrupt `struct amdgpu_device` and dereference type-confused pointers during display init, crashing the kernel or leaving the machine
