              "value": "AV:L - The vulnerable parser only runs against on-disk NTFS metadata, so the attacker must get a crafted image mounted locally (attacker-supplied removable media auto-mounted by udisks2/autofs, a loop-mounted image, or a privileged container) and then reach `hdr_find_e()` with a local `stat()`/`open()` on a path inside the malicious directory. No remote peer or network protocol touches this code.\nAC:L - The wrap is deterministic and fully attacker-authored: setting `de_off` to `0xFFFFFFF0` in the crafted index root defeats both `index_hdr_check()` and `hdr_find_e()`\u0027s gate every time, and the resulting `offs[0] = 0xFFF0` entry is reached by the very first binary-search step. No race, no timing window, and the 32-bit kernel is a property of the targeted deployment (i686 distros, ARM32 embedded/industrial, 32-bit Android) rather than a condition the attacker must win.\nPR:L - Mounting `ntfs3` nominally needs `CAP_SYS_ADMIN` (no `FS_USERNS_MOUNT`), but on desktop, kiosk and shared-workstation deployments an ordinary logged-in user gets attacker-supplied media mounted for them by udisks2/polkit, and every step that actually drives the bug \u2014 the path lookup, the file write that triggers `ni_update_parent()` \u2014 is an unprivileged file operation. Scoring the lower-privilege reachable path.\nUI:N - No second user has to act: the automounter mounts the attacker\u0027s own device without any victim interaction, and the attacker then performs the triggering `stat()`, `ftruncate()` and writeback themselves. In the loop-mount and privileged-container variants the attacker likewise performs the mount directly.\nS:U - The out-of-bounds reads and the `indx_update_dup()` write all land in kernel slab memory and stay within the kernel\u0027s own security authority \u2014 no hypervisor, IOMMU, or container/VM boundary is crossed.\nC:H - `Add2Ptr(hdr, offs[mid_idx])` yields a pointer 65520 bytes past a 1 KB MFT record or 4 KB index buffer, and that OOB memory is then interpreted as a directory entry \u2014 its `ref` field is passed to `ntfs_iget5()`, and `cmp_fnames()` compares its name bytes against the attacker\u0027s lookup string, giving a repeatable oracle that lets the attacker read back adjacent kernel heap contents byte by byte.\nI:H - The out-of-bounds entry pointer returned by `hdr_find_e()` flows into `indx_update_dup()`, whose `memcpy(\u0026e_fname-\u003edup, dup, sizeof(*dup))` performs a 0x38-byte heap write ~64 KB out of bounds with content the attacker chooses (`data_size`/`alloc_size` via `ftruncate`, four timestamps via `utimensat`) \u2014 a controlled OOB write suitable for corrupting adjacent slab objects and hijacking control flow.\nA:H - A read 65520 bytes past a small kmalloc allocation reliably faults on unmapped memory or trips KASAN/KFENCE, and the `WARN_ON(!e)` in `indx_insert_into_root()` fires on the same corrupted pointer, so a single `stat()` on the crafted mount oopses or panics the kernel."
