"value": "AV:L - The vulnerable paths are reached only through ioctls on the local `/dev/kfd` character device (`kfd_ioctl_create_queue`, `kfd_ioctl_destroy_queue`) and through process teardown in `kfd_process_destroy_pdds()`. No network or adjacent-network exposure exists.\nAC:L - The attacker fully controls queue creation/destruction and process exit, so the free of the `amdgpu_bo` and the subsequent reuse of the stale pointer are directly and repeatably triggerable with no race or memory-layout condition outside the attacker\u0027s influence. Standard heap grooming from userspace controls what reoccupies the freed object.\nPR:L - `kfd_open()` performs no capability check; any local user holding a file descriptor on `/dev/kfd` (render group on desktops, or the device node passed directly into ROCm containers) can drive the paths. No root or CAP_SYS_ADMIN is needed.\nUI:N - The attacker triggers everything from its own process via ioctls and normal process exit; no action by another user or administrator is required.\nS:U - The corruption stays within the kernel\u0027s own memory and security authority \u2014 it is standard in-kernel memory corruption, not a hypervisor, IOMMU, or sandbox boundary crossing.\nC:H - Use-after-free on a `struct amdgpu_bo` lets the attacker reclaim the freed slab object with attacker-shaped data and have the driver dereference it (e.g. `amdgpu_bo_gpu_offset(q-\u003ewptr_bo)`, kmap/CPU-pointer fields), yielding an arbitrary kernel-memory read primitive and disclosure of kernel addresses and contents.\nI:H - The same UAF gives a write primitive \u2014 the freed `amdgpu_bo` is subsequently written through (`amdgpu_bo_kunmap`, `amdgpu_bo_unpin`, refcount and TTM list manipulation) and contains function-pointer-bearing sub-structures, so heap spraying can be leveraged into controlled writes and control-flow hijack for privilege escalation.\nA:H - Even without full exploitation, dereferencing and double-unref\u0027ing a freed buffer object corrupts TTM/slab state and reliably produces an oops or kernel panic, taking down the machine \u2014 and it is triggerable repeatedly by any local user with GPU access."

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.
Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
