No network protocol is involved.\nAC:L - The attacker fully controls `attr-\u003esize` in the image, and any value \u003e= 0x100000000 - off deterministically wraps the `off + asize \u003e used` check; there is no race and no dependence on memory layout to reach the out-of-bounds access.\nPR:L - ntfs3 lacks FS_USERNS_MOUNT, but on the realistic desktop/kiosk/embedded/automotive deployments an unprivileged console user can mount attacker-supplied NTFS removable media through udisks2/policykit automount or an fstab `user` entry, so basic local user privileges suffice.\nUI:N - The attacker performs the mount themselves, or the crafted volume is automounted on insertion; no separate victim action is required, and on an already-mounted hostile image any inode lookup re-enters `mi_enum_attr()`.\nS:U - The corruption is confined to kernel slab memory within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The bogus ~4 GB `asize` neutralizes the resident-data checks, letting `ntfs_load_attr_list()` memcpy an attacker-chosen `data_size` out of a ~1 KB record buffer, and `run_unpack()` read past the slab (KASAN caught it landing in a neighbouring UDP socket object) \u2014 a large kernel heap disclosure whose contents are reflected into parsed structures and back to the image.\nI:H - `mi_resize_attr()`/`mi_remove_attr()` use `Add2Ptr(attr, asize)` with a wrapped-positive `tail`, producing out-of-bounds memmove/memset writes through a wild pointer, and runlists synthesized from out-of-bounds heap bytes redirect file data to arbitrary volume clusters.\nA:H - The commit documents a KASAN slab-out-of-bounds oops at mount time, and the unbounded reads plus wild-pointer writes readily fault into unmapped memory, causing a kernel panic."
