Vulnerability from fkie_nvd - Published: 2025-04-16 15:16 - Updated: 2026-07-30 06:22

Severity

7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
7.1 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H

Summary

In the Linux kernel, the following vulnerability has been resolved: ocfs2: validate l_tree_depth to avoid out-of-bounds access The l_tree_depth field is 16-bit (__le16), but the actual maximum depth is limited to OCFS2_MAX_PATH_DEPTH. Add a check to prevent out-of-bounds access if l_tree_depth has an invalid value, which may occur when reading from a corrupted mounted disk [1].

It is not reachable via any network protocol handler.\nAC:L - The attacker fully controls the on-disk `l_tree_depth` fields and the extent-block chain, so the descent depth \u2014 and therefore the number of out-of-bounds `p_node[]` slots written \u2014 is deterministic; no race or uncontrollable precondition is involved (metaecc checksums are trivially computed by the attacker, and the feature may be off entirely).\nPR:L - An unprivileged local user suffices in realistic deployments: desktop/kiosk automounters (udisks2) mount attacker-supplied removable media, and on an already-mounted volume any user with file access drives `ocfs2_find_path()` via write/truncate/punch-hole/reflink. Real root in the initial namespace is not required for the trigger itself.\nUI:N - No separate victim action is needed \u2014 an automounter mounts the attacker\u0027s device automatically, and in OCFS2\u0027s native shared-disk cluster deployment the corrupted extent block is written to shared storage and consumed by peer nodes on an already-mounted filesystem during normal file I/O.\nS:U - The out-of-bounds write corrupts kernel slab memory within the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The overflow writes kernel `buffer_head`/`ocfs2_extent_list` pointers into adjacent kmalloc-96 slab objects, corrupting neighbouring structures in a way that is leverageable into an arbitrary-read primitive and leaks kernel pointer values into adjacent state.\nI:H - This is an unbounded out-of-bounds heap write (a cyclic extent-block chain lets the index grow without limit), overwriting adjacent slab objects with kernel pointers \u2014 a classic heap-corruption primitive exploitable for control-flow hijack and privilege escalation.\nA:H - Corrupting neighbouring slab objects with pointer values reliably produces a kernel oops/panic, and the crafted chain can also loop indefinitely while scribbling over memory, taking the machine down."

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.
