No network or remote-peer input reaches this code.\nAC:L - Every value driving the overflow (`rst->attr_names_len`, `open_attr_len`, and each `ATTR_NAME_ENTRY.off`/`name_bytes`) comes verbatim from the attacker-authored `$LogFile`, so the out-of-bounds walk and the controlled-offset write trigger deterministically on the first mount with no race and no reliance on conditions outside the attacker's control.\nPR:L - On the realistic target (shared workstation, kiosk, automotive/embedded head unit) an unprivileged local user with a session can get a crafted NTFS volume mounted through udisks2/polkit removable-media automount or an fstab/mount helper, so basic local user access suffices rather than real root.\nUI:N - In the automount scenario the attacker triggers the mount themselves by attaching the media; no separate victim has to open a file, run a command, or take any action for `log_replay()` to parse the malicious log.\nS:U - The corruption is confined to kernel heap memory within the same kernel security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - The unbounded `while (ane->off)` walk reads far past the end of the `attr_names` slab allocation, and the resulting heap corruption of adjacent slab objects (including planting a kernel heap pointer into neighbouring structures) is leverageable into broad kernel memory disclosure.\nI:H - `Add2Ptr(oatbl, le16_to_cpu(ane->off))` gives an attacker-chosen offset of up to 65535 bytes beyond a small `kmemdup()` allocation, at which the code writes an 8-byte kernel pointer plus two attacker-influenced bytes \u2014 a controlled out-of-bounds heap write suitable for overwriting adjacent objects and hijacking control flow.\nA:H - Even without full exploitation, the out-of-bounds reads and writes reliably corrupt slab memory or hit unmapped pages during mount, producing an oops or panic." } } }
