              "value": "AV:L - The only trigger is `mount(2)` of a crafted f2fs image whose superblock `devs[].path` is a full 64 bytes with no terminator (`get_tree_bdev` \u2192 `f2fs_fill_super` \u2192 `f2fs_scan_devices`), and the resulting disclosure is read back locally via `/proc/fs/f2fs/\u003cdev\u003e/disk_map`. No network or peer-supplied data reaches this code; between Physical (removable media) and Local, the higher-severity Local applies.\nAC:L - The attacker fully controls the on-disk `f2fs_device.path[64]` bytes and the adjacent `total_segments` value, so filling the path completely deterministically leaves `sbi-\u003edevs[i].path` unterminated on every mount \u2014 exactly as the reporter demonstrated. There is no race, no memory-layout guessing, and the trailing struct fields (`start_blk`/`end_blk`) are deterministically derived from segment counts the attacker chooses.\nPR:N - The attacker needs no account or privileges on the victim system \u2014 only delivery of a malicious f2fs image on an SD card, USB stick, or disk image that a privileged auto-mount daemon (Android vold, udisks2) or administrator later processes, which is the most severe reasonable scenario for f2fs given its role as the standard Android/removable-media filesystem.\nUI:R - f2fs does not set `FS_USERNS_MOUNT`, so mounting requires `CAP_SYS_ADMIN` in the initial user namespace; the crafted image therefore reaches the vulnerable code only when a victim inserts the media or mounts the image, and that mount action constitutes user interaction.\nS:U - The over-read, the leaked slab contents, and any resulting fault all remain within the kernel\u0027s own security authority on the host performing the mount; no VM, container, or IOMMU boundary is crossed.\nC:H - The unterminated string is read until an arbitrary in-memory NUL, so the length is determined by heap contents rather than by any bound: the over-read spills into `total_segments`/`start_blk`/`end_blk`, into `nr_blkz` and the `blkz_seq` kernel heap pointer on zoned devices, and past the end of the `kzalloc`\u0027d `f2fs_dev_info` array at its last element. Those bytes are printed verbatim into dmesg and exported through the world-readable 0444 `/proc/fs/f2fs/\u003cdev\u003e/disk_map`, so adjacent slab data and a kernel heap pointer (defeating KASLR) are disclosed to unprivileged userspace and can be re-read at will.\nI:L - The mis-parsed string is handed to `bdev_file_open_by_path()`, so f2fs can attach to and write filesystem data onto a block device whose path exceeds the 64-byte on-disk field \u2014 a target the format otherwise cannot name \u2014 corrupting that device\u0027s contents. There is no out-of-bounds write or attacker-controlled store, so the modification is limited rather than arbitrary.\nA:H - The strlen/vsnprintf walk past the end of the slab object faults hard on hardened configurations (KFENCE guard page, `panic_on_warn` with a KASAN slab-out-of-bounds report) and can read into unmapped memory at a slab-page boundary, oopsing the mounting task. Even without a fault, the mis-parsed device path aborts the mount with \"Failed to find devices\", leaving the volume \u2014 typically the device\u0027s primary Android/SD-card storage \u2014 unusable."
