There is no network or remote-peer path into amdgpu_cs_pass1().\nAC:L - The attacker directly supplies the overflowing value (length_dw \u003e= 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 \u2014 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\u0027s 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\u0027s 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 \u2014 attacker-groomable via page spraying \u2014 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."
