"value": "AV:L - The vulnerable code is reached only by presenting a crafted NTFS volume to the local kernel as a block device — a USB stick on an automounting kiosk/NAS/infotainment unit, or a loop/NBD-backed image mounted via udisks2 — driving mount(2) and the subsequent index walks in fs/ntfs3/index.c. No network protocol handler is involved, and physical access is not strictly required since loop and network-block-backed images work equally well.\nAC:L - Every input to the wrap — hdr->de_off, hdr->used, hdr->total, the entry size fields, and the attribute-list layout that steers which header escapes index_hdr_check() — is an attacker-chosen byte in the image, so the corruption is deterministic with no race to win and no dependency on kernel memory layout the attacker cannot influence. The 32-bit size_t requirement is a property of the target the attacker selects, and ntfs3 automounting removable NTFS media on 32-bit ARM NAS boxes, media players, and embedded appliances is the driver's canonical deployment rather than a rare configuration.\nPR:N - The attacker needs no account or credential on the target — they only supply the malicious filesystem image, which is then mounted by root, by an automount daemon such as udisks2/systemd, or by a container/VM image-handling service acting on the attacker's data. Every privileged operation along the path is performed by the victim system on the attacker's behalf; where a local account does exist, desktop polkit loop-mount brokering provides the same reach at even lower cost.\nUI:N - On kiosks, NAS appliances, and infotainment systems that automount removable media, inserting the device triggers the mount with no human participation, and the index code runs unattended during mount itself via ntfs_security_init()'s indx_init()/indx_find() on the $SDH/$SII trees rather than waiting for a subsequent file access. In the loop-device scenario the attacker performs the mount themselves, so no separate victim action is required either.\nS:U - The wrapped pointer arithmetic, out-of-bounds reads, and memmove/memcpy writes all occur in kernel heap memory within the same kernel security authority that hosts the vulnerable ntfs3 code. No VM, IOMMU, hypervisor, or sandbox boundary is crossed.\nC:H - The wrapped pointer makes hdr_first_de() return an NTFS_DE outside the index buffer, and because hdr_next_de()'s bound check wraps identically with used near UINT_MAX, the entry walk proceeds past the allocation reading adjacent kernel heap as entry headers. Those bytes are consumed as file names, key_size, and MFT references and handed to userspace through ntfs_dir_emit()/dir_emit() during readdir, and steer de_get_vbn()-driven follow-on reads, making adjacent kernel memory directly observable.\nI:H - The same out-of-bounds entry pointer is passed to the mutation paths — hdr_insert_de() performs memmove(Add2Ptr(before, de_size), before, used - off) and memcpy(before, de, de_size) through it, hdr_delete_de() memmoves through it, and indx_delete_entry() applies le16_sub_cpu()/le32_sub_cpu() to fields at that address — yielding an out-of-bounds write of attacker-chosen bytes into kernel heap adjacent to the MFT-record or index-block allocation. Controlled heap overwrite of that form is a usable memory-corruption primitive for control-flow hijack, and the corrupted headers are additionally written back to disk by indx_write().\nA:H - Dereferencing and walking a pointer built from wrapped 32-bit arithmetic reads and writes past the kmalloc'd index buffer, producing slab corruption and oops/panic (KASAN-class out-of-bounds), and the resulting nonsensical index geometry drives _ntfs_bad_inode()/-EINVAL error paths across the mounted volume. The fault occurs during mount or the first directory operation and can be reproduced on every mount attempt of the crafted image."
