"value": "AV:L - The defect is in the amdgpu ring/scheduler registration path executed during local device and driver initialization, and the corrupted `gpu_sched[][]` table is consumed only through local DRM ioctls on /dev/dri/card*/renderD*. There is no network or adjacent-network path into amdgpu ring init.\nAC:L - In an affected configuration the ring type is a compile-time constant, so the out-of-bounds index is deterministic on every initialization — there is no race to win and no memory-layout condition to guess.\nPR:L - No capability check or privilege gate protects the array indexing itself; it runs as part of ordinary device attach/probe, and the resulting scheduler table is subsequently read and dereferenced on behalf of unprivileged local users holding a DRM render-node fd (amdgpu_ctx.c:163/229). Real root in the init namespace is not required to consume the corrupted state.\nUI:N - The write occurs automatically during driver/device initialization and the corrupted table is used by the attacker's own context-creation and command-submission ioctls; no action by another user or victim is needed.\nS:U - The corruption and its consequences are confined to the kernel of the machine running the driver, within `struct amdgpu_device`; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The code reads a `num_scheds` counter from out-of-bounds memory and uses it as an unbounded write index, and the resulting corruption of adjacent `struct amdgpu_irq` state (interrupt source tables and callback pointers) is memory corruption that can be leveraged for disclosure of kernel memory.\nI:H - This is an out-of-bounds write of a kernel pointer (`&ring->sched`) past `gpu_sched[][]` at an index taken from out-of-bounds memory, overwriting adjacent interrupt-handling structures in `struct amdgpu_device`; per kernel scoring guidance an OOB write with a corrupted destination index is High, as it can be leveraged toward control-flow hijack.\nA:H - Corrupting the scheduler table and adjacent irq structures leaves stale or wild `drm_gpu_scheduler` pointers that are later dereferenced during entity setup and interrupt dispatch, producing a kernel oops and a wedged GPU/system."
