"value": "AV:L - The vulnerability is reached only through the DRM_IOCTL_AMDGPU_CS ioctl on a local amdgpu device node (/dev/dri/renderD* or card*), requiring local access to the machine. There is no network or remote-peer path into amdgpu_cs_pass1().\nAC:L - The attacker directly supplies the overflowing value (length_dw >= 0x40000000) in a single ioctl call with no race, timing, or memory-layout condition to win, and can free memory and retry to make the large allocation succeed. On the multi-GiB systems where AMD GPUs are deployed (workstations, Steam Deck, cloud GPU nodes) the allocation reliably succeeds.\nPR:L - AMDGPU_CS is registered with DRM_RENDER_ALLOW, so no DRM master, authentication, or capability is required — any unprivileged local user or sandboxed app holding an fd on the render node can invoke it, which is standard for desktop sessions, Android apps, and GPU-enabled containers.\nUI:N - Exploitation is a self-contained sequence of ioctls issued by the attacker's own process; no victim action, file open, or mount is needed.\nS:U - The corrupted state and the uninitialized data consumed all live within the kernel's own security authority on the same host; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - A multi-gigabyte kvmalloc/vmalloc buffer is left completely uninitialized and then consumed as GEM handles, BO-list descriptors, user pointers and fence offsets, exposing stale kernel/page contents; the resulting lookup success/failure and the observable fence write offset form oracles that let an attacker read back that uninitialized kernel memory.\nI:H - Uninitialized kernel memory — attacker-groomable via page spraying — is used as GPU virtual addresses, IB sizes, flags, buffer-object handles and __user pointers that drive command submission, BO list construction and the user-fence write target, giving control-relevant fields that can be steered toward memory corruption.\nA:H - An unprivileged caller can force repeated 4 GiB kernel allocations causing reclaim storms and OOM kills, trips a WARN_ON_ONCE() in kvmalloc_node() (a panic under panic_on_warn), and drives the CS parser through uninitialized state, producing kernel crashes and denial of service."
