Title
xfs: don't swallow dquot recovery verification errors
Summary
In the Linux kernel, the following vulnerability has been resolved:
xfs: don't swallow dquot recovery verification errors
xlog_recover_dquot_commit_pass2() validates the recovered dquot with
xfs_dqblk_verify() and, on failure, sets error = -EFSCORRUPTED and jumps
to out_release. But out_release unconditionally returns 0, so the
corruption error is discarded: the caller xlog_recover_items_pass2()
sees success, log recovery proceeds as if the dquot were valid, and the
corrupt quota buffer can be written back to disk.
Severity
No CVSS data available.

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.
