There is no remote or adjacent-network path to this code.\nAC:L - The error path is entered when the metadata DMA mapping fails, which an attacker can drive by flooding concurrent I/O to exhaust swiotlb bounce-buffer slots or IOVA space (guaranteed bounce-through in confidential-compute guests or DMA-mask-limited setups), and the stale `iod` state is deterministic once the path is taken. No timing race the attacker cannot control is involved.\nPR:L - Only an unprivileged local user with access to an NVMe namespace is required \u2014 normal file I/O on a PI/metadata-formatted namespace sets `REQ_INTEGRITY` with no capability at all, and `nvme_cmd_allowed()` explicitly permits unprivileged passthrough of non-intrusive I/O commands without `CAP_SYS_ADMIN`.\nUI:N - The attacker triggers the condition entirely through its own I/O submissions; no action by another user or administrator is needed.\nS:U - The corruption is confined to kernel memory and DMA mappings managed by the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - `nvme_unmap_data()` reads a stale, already-freed `iod-\u003esgt.sgl` scatterlist, and the resulting mempool double-free lets two concurrent requests share one SGL so one request\u0027s data can be steered into another\u0027s buffers; spurious `dma_unmap_page()` of a reassigned IOVA can likewise expose unrelated memory contents to the device.\nI:H - The double `mempool_free()` of the scatterlist is a heap double-free primitive suitable for controlled heap corruption, and tearing down a DMA mapping that has been reallocated leaves the device DMA-writing into memory now owned by other subsystems \u2014 both give arbitrary-write-class integrity impact.\nA:H - The path hits `WARN_ON_ONCE()` and then unmaps DMA using garbage addresses and frees an invalid pointer, producing IOMMU faults, slab/mempool corruption, and kernel oops or panic."

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.
