Title
fs/ntfs3: Validate ff offset
Summary
In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Validate ff offset This adds sanity checks for ff offset. There is a check on rt->first_free at first, but walking through by ff without any check. If the second ff is a large offset. We may encounter an out-of-bound read.

No network or remote peer is involved, and the image can be supplied as a local file/loop device rather than requiring physical media, so Local is the correct (and higher-severity) vector versus Physical.\nAC:L - Every field driving the bug (`rt-\u003esize`, `rt-\u003eused`, `rt-\u003efirst_free`, `rt-\u003elast_free`, and the free-list words) is attacker-authored data in the image, so the out-of-bounds offset is chosen deterministically with no race, memory-layout guess, or environmental precondition.\nPR:L - ntfs3 is `FS_REQUIRES_DEV` without `FS_USERNS_MOUNT`, so mounting is not reachable from an unprivileged user namespace, but on desktop/kiosk/workstation deployments an ordinary logged-in local user can get an attacker-supplied NTFS volume mounted via udisks2/automount policy without any administrative credential.\nUI:N - The attacker performs the mount themselves (or automount/udisks2 does it the moment the device appears) and log replay runs unconditionally on every mount, read-only included; no separate victim has to open a file or take any action.\nS:U - The out-of-bounds accesses occur in kernel memory within the same security authority that already owns the mount; no hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The unvalidated free-list walk performs 4-byte reads at attacker-chosen offsets of up to ~4 GB beyond the slab object, and the walk\u0027s outcome (terminate, hit `RESTART_ENTRY_ALLOCATED`, or spin) is observable through mount success/failure, turning the wild reads into a probing oracle over kernel heap contents.\nI:H - Because `check_rstbl()` is the sole validator of `first_free`/`last_free` before the tables reach `free_rsttbl_idx()`, `alloc_rsttbl_idx()`, and `extend_rsttbl()`, a corrupted list yields out-of-bounds 4-byte slab writes with attacker-influenced values (`*(__le32 *)Add2Ptr(rt, lf) = off_le`, `*last_e = *e`), which is heap corruption usable for control-flow-relevant metadata overwrite.\nA:H - A wild read up to 4 GB from the buffer readily faults on unmapped kernel memory, producing an oops/panic, and a cyclic free list makes the unbounded `for (off = ff; off;)` / `for (;;)` walks loop forever with no reschedule, hanging the mounting task and CPU."

No network or remote peer is involved, and the image can be supplied as a local file/loop device rather than requiring physical media, so Local is the correct (and higher-severity) vector versus Physical.\\nAC:L - Every field driving the bug (`rt-\u003esize`, `rt-\u003eused`, `rt-\u003efirst_free`, `rt-\u003elast_free`, and the free-list words) is attacker-authored data in the image, so the out-of-bounds offset is chosen deterministically with no race, memory-layout guess, or environmental precondition.\\nPR:L - ntfs3 is `FS_REQUIRES_DEV` without `FS_USERNS_MOUNT`, so mounting is not reachable from an unprivileged user namespace, but on desktop/kiosk/workstation deployments an ordinary logged-in local user can get an attacker-supplied NTFS volume mounted via udisks2/automount policy without any administrative credential.\\nUI:N - The attacker performs the mount themselves (or automount/udisks2 does it the moment the device appears) and log replay runs unconditionally on every mount, read-only included; no separate victim has to open a file or take any action.\\nS:U - The out-of-bounds accesses occur in kernel memory within the same security authority that already owns the mount; no hypervisor, IOMMU, or sandbox boundary is crossed.\\nC:H - The unvalidated free-list walk performs 4-byte reads at attacker-chosen offsets of up to ~4 GB beyond the slab object, and the walk\u0027s outcome (terminate, hit `RESTART_ENTRY_ALLOCATED`, or spin) is observable through mount success/failure, turning the wild reads into a probing oracle over kernel heap contents.\\nI:H - Because `check_rstbl()` is the sole validator of `first_free`/`last_free` before the tables reach `free_rsttbl_idx()`, `alloc_rsttbl_idx()`, and `extend_rsttbl()`, a corrupted list yields out-of-bounds 4-byte slab writes with attacker-influenced values (`*(__le32 *)Add2Ptr(rt, lf) = off_le`, `*last_e = *e`), which is heap corruption usable for control-flow-relevant metadata overwrite.\\nA:H - A wild read up to 4 GB from the buffer readily faults on unmapped kernel memory, producing an oops/panic, and a cyclic free list makes the unbounded `for (off = ff;
