"value": "AV:L - The vulnerable extent-walk code is reached only through a locally mounted UDF filesystem backed by an attacker-crafted image (ISO, loop device, or removable medium), then exercised by ordinary local file I/O syscalls. UDF is not a network-facing service, so there is no remote or adjacent-network path to this code.\nAC:L - The attacker fully controls the on-disk `lengthAllocDescs` field, so producing the integer overflow and the negative `alen` that defeats the bounds check is deterministic; no race, no memory-layout luck, and no attacker-uncontrollable precondition is involved. A simple read or close of a file on the crafted image triggers the walk every time.\nPR:N - The attacker needs no account or privileges on the target system \u2014 supplying a malicious UDF image (USB stick, ISO download, or exported disk image) is sufficient, and all attacker-controlled state lives in the image itself. This matches the scoring of the sibling `lengthAllocDescs` bug CVE-2025-40044.\nUI:R - UDF sets only `FS_REQUIRES_DEV` (no `FS_USERNS_MOUNT`), so the image cannot be mounted from an unprivileged user namespace; a privileged user or automount daemon must mount the attacker-supplied medium before the flaw becomes reachable.\nS:U - The out-of-bounds accesses stay within kernel memory of the same system with no crossing of a virtualization, IOMMU, or sandbox boundary. This is a conventional in-kernel memory-safety defect.\nC:H - The defeated bounds check yields an unbounded out-of-bounds read of kernel heap/page memory interpreted as extent descriptors, and `udf_update_tag()`/`crc_itu_t()` additionally reads far past the buffer. The leaked values become block mappings observable through file reads, giving an oracle for adjacent kernel memory contents.\nI:H - `udf_write_aext()` writes an 8-byte attacker-influenced `short_ad`/`long_ad` at `epos-\u003ebh-\u003eb_data + epos-\u003eoffset` after `epos-\u003eoffset` has been advanced past the buffer without bound, producing a controllable out-of-bounds heap write reachable from truncate/delete/insert extent paths. Such a write primitive is leverageable for kernel data corruption and control-flow hijacking.\nA:H - The wild reads and writes at large offsets past the buffer readily hit unmapped or unrelated memory, causing KASAN/KMSAN reports, corruption of neighbouring kernel objects, and kernel oops or panic. The condition is reproducible on demand from the crafted image."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
