CVE-2023-53804 (GCVE-0-2023-53804)

Vulnerability from cvelistv5 – Published: 2025-12-09 00:01 – Updated: 2026-08-05 09:16

Title

nilfs2: fix use-after-free bug of nilfs_root in nilfs_evict_inode()

Summary

In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix use-after-free bug of nilfs_root in nilfs_evict_inode() During unmount process of nilfs2, nothing holds nilfs_root structure after nilfs2 detaches its writer in nilfs_detach_log_writer(). However, since nilfs_evict_inode() uses nilfs_root for some cleanup operations, it may cause use-after-free read if inodes are left in "garbage_list" and released by nilfs_dispose_list() at the end of nilfs_detach_log_writer(). Fix this issue by modifying nilfs_evict_inode() to only clear inode without additional metadata changes that use nilfs_root if the file system is degraded to read-only or the writer is detached.

Severity

7.8 (High)

However, since\nnilfs_evict_inode() uses nilfs_root for some cleanup operations, it may\ncause use-after-free read if inodes are left in \"garbage_list\" and\nreleased by nilfs_dispose_list() at the end of nilfs_detach_log_writer().\n\nFix this issue by modifying nilfs_evict_inode() to only clear inode\nwithout additional metadata changes that use nilfs_root if the file system\nis degraded to read-only or the writer is detached."

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.
