Summary

In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix nilfs_empty_dir() misjudgment and long loop on I/O errors The error handling in nilfs_empty_dir() when a directory folio/page read fails is incorrect, as in the old ext2 implementation, and if the folio/page cannot be read or nilfs_check_folio() fails, it will falsely determine the directory as empty and corrupt the file system. In addition, since nilfs_empty_dir() does not immediately return on a failed folio/page read, but continues to loop, this can cause a long loop with I/O if i_size of the directory's inode is also corrupted, causing the log writer thread to wait and hang, as reported by syzbot. Fix these issues by making nilfs_empty_dir() immediately return a false value (0) if it fails to get a directory folio/page.

              "value": "AV:L - The vulnerable code is reached through the local `rmdir(2)`/`rename(2)` syscall path on a mounted nilfs2 filesystem, with the malicious directory state supplied by a crafted nilfs2 image (automounted removable media, loop-mounted file, or admin-mounted volume). No network protocol handler is involved in the vulnerable function itself.\nAC:L - The attacker fully controls the on-disk directory: setting a corrupt `rec_len`/alignment/inode number so `nilfs_check_folio()` deterministically fails, and setting a huge `i_size` (read unvalidated at `inode.c:412`) so `dir_pages()` yields ~2^51 iterations. Both the false \"empty\" verdict and the segctor-sem hang follow deterministically with no race, timing window, or memory-layout dependency.\nPR:L - Once the filesystem is mounted, any ordinary unprivileged local user with write access to a directory on it triggers the bug with a single `rmdir()` or `rename()` \u2014 no capability, no root, and no `CAP_SYS_ADMIN` is needed for the triggering syscall itself.\nUI:N - No action by a second user is required: on a kiosk, desktop, or embedded system with udisks2/systemd automount, inserting the crafted volume is performed by the attacker and mounting is done by a daemon, after which the attacker issues the `rmdir()` themselves.\nS:U - The damage \u2014 corrupted nilfs2 metadata and a wedged log-writer thread \u2014 stays entirely within the kernel\u0027s own security authority on the affected host; no VM, IOMMU, or sandbox boundary is crossed.\nC:N - The defect is an incorrect boolean return, not a memory-safety violation: `nilfs_check_folio()` still bounds every entry walk, and the `fail:` label in `nilfs_get_folio()` already releases the folio, so there is no out-of-bounds read, no use-after-free, and no kernel pointer or adjacent-memory disclosure.\nI:H - The false \"directory is empty\" verdict lets `nilfs_rmdir()` unlink a populated directory (`i_size = 0`, `drop_nlink()`) and lets `nilfs_rename()` overwrite one, orphaning the entire subtree and, as the fix states, corrupting the file system \u2014 silent, unauthorized destruction of stored data and metadata that the kernel then continues to operate on.\nA:H - With a corrupted `i_size` the loop performs an effectively unbounded sequence of failing reads with no `cond_resched()` or signal check while holding `ns_segctor_sem` for read and `sb_start_intwrite()`, so the segctord log writer blocks forever on `down_write()` \u2014 the syzbot hung-task hang \u2014 stalling all writeback, sync, freeze, and umount on that filesystem and panicking the box if `hung_task_panic` is set."

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

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.
