Title
btrfs: don't BUG_ON() when 0 reference count at btrfs_lookup_extent_info()
Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: don't BUG_ON() when 0 reference count at btrfs_lookup_extent_info()
Instead of doing a BUG_ON() handle the error by returning -EUCLEAN,
aborting the transaction and logging an error message.

"value": "AV:L - The vulnerable path is reached through a locally attached btrfs filesystem \u2014 a crafted image on a USB stick, loop-mounted file, or container/VM disk image \u2014 and then driven by ordinary local file writes or subvolume deletion. There is no network-facing consumer of btrfs_lookup_extent_info().\nAC:L - The triggering condition is a static, fully attacker-controlled on-disk value (extent item refs == 0) that the tree checker does not reject, so the crafted image deterministically hits the BUG_ON on the first COW or snapshot-delete of the affected block. No race, timing window, or memory-layout dependency is involved.\nPR:L - Once a crafted or inconsistent btrfs is mounted \u2014 routinely via desktop/kiosk automount (udisks2/systemd), shared storage, or container images \u2014 any unprivileged local user with write access drives btrfs_force_cow_block()/btrfs_drop_snapshot() into the assertion; no capability check gates the path.\nUI:N - After the filesystem is present, the attacker triggers the fault entirely through their own file writes or a subvolume delete, with no action required from any other user. Automount removes the need for a victim to explicitly mount the device.\nS:U - The crash and any resulting metadata corruption are confined to the kernel and the affected btrfs filesystem, within the same security authority. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The assertion is btrfs\u0027s last line of defense before operating on an extent with broken reference bookkeeping; when it is bypassed (CONFIG_BUG=n embedded/IoT builds) update_ref_for_cow() takes the last-reference path and frees a still-referenced tree block, producing cross-linked extents that expose one file\u0027s or subvolume\u0027s data through another. The oops itself also dumps kernel registers, stack contents, and pointers to the log.\nI:H - Continuing past a zero refcount causes btrfs to free and re-allocate live metadata blocks, giving the attacker arbitrary corruption of extent-tree and file data belonging to other users on the filesystem. The oops additionally aborts a transaction mid-flight, leaving on-disk state inconsistent.\nA:H - BUG_ON() panics the kernel outright under panic_on_oops; otherwise the task is killed while still holding delayed_refs-\u003elock, head-\u003emutex, and tree locks, so every subsequent delayed-ref operation on that filesystem spins or blocks forever \u2014 an unrecoverable filesystem-wide hang and potential hard lockup, which is exactly why the fix unlocks all three before returning -EUCLEAN."

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.
