"value": "AV:L - The affected code is the ntfs3 local filesystem name/label handling, reached through ordinary VFS syscalls (open/creat/link/rename/lookup) on a mounted volume or a write to /proc/fs/ntfs3/\u003cdev\u003e/label. No network protocol handling is involved.\nAC:L - Triggering is fully deterministic \u2014 the attacker simply supplies a name or label longer than 10 UTF-16 units, and the copy length is directly attacker-controlled. There is no race, no memory-layout dependency, and no condition outside the attacker\u0027s control.\nPR:L - While the ntfs_set_label() path is root-gated, the identical mis-sized cpu_str accesses in fill_name_de(), ntfs_lookup(), ntfs_d_hash() and ntfs_d_compare() are reached by any unprivileged user creating, renaming, linking or merely looking up a long file name on an already-mounted ntfs3 volume.\nUI:N - No victim action is required once an ntfs3 volume is mounted, which is the normal state on desktops, kiosks, Android and media devices with USB/NTFS storage; the attacker acts entirely on their own.\nS:U - The corruption stays within kernel memory under the same security authority; there is no VM, IOMMU or sandbox boundary crossed.\nC:H - Up to 256 bytes (label path) and 510 bytes (name path) are read out of a 20-byte-declared array, an out-of-bounds read far beyond a few bounded bytes that can disclose adjacent kernel heap contents into on-disk name/label attributes readable by the attacker.\nI:H - The same paths write up to 510 bytes through the 20-byte-declared name member with attacker-controlled length and content, an out-of-bounds write that is the classic primitive for adjacent-object corruption and control-flow hijack.\nA:H - Out-of-declared-bounds access of this size corrupts or over-reads adjacent kernel heap state and trips CONFIG_FORTIFY_SOURCE field-spanning detection, resulting in kernel warnings, oops or panic (fatal with panic_on_warn)."

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.
