Previously, some sanity check have been done in dump_mapping() before
the print facility parsing '%pd' though, it's still possible to run into
an invalid dentry.d_name.name.
Since dump_mapping() only needs to dump the filename only, retrieve it
by itself in a safer way to prevent an unnecessary crash.
Note that either retrieving the filename with '%pd' or
strncpy_from_kernel_nofault(), the filename could be unreliable.

"value": "AV:L - The vulnerable code is reached only through local kernel activity \u2014 page-cache/dentry churn plus a memory offline or page-state anomaly on the same machine \u2014 with no network-facing entry point. There is no remote protocol handler anywhere on the path from `dump_page()` to `dump_mapping()`.\nAC:L - Both sides of the race are attacker-influenceable: the attacker pins page-cache folios so `isolate_folio_to_list()`/`migrate_pages()` fail and force the `dump_page()` call, while concurrently renaming/unlinking long-named files to free the `external_name` allocation that `d_name.name` points at. Per the race-condition guidance, an attacker who creates both sides of the window scores Low.\nPR:L - An ordinary unprivileged user creates the entire vulnerable condition \u2014 the stale `d_name.name` pointer and the pinned/unmovable page-cache folios that trigger the dump \u2014 needing only normal filesystem and memory syscalls. In CXL tiering, virtio-mem, and balloon deployments the offline side is automated infrastructure rather than an operator action, so no elevated privilege is required of the attacker.\nUI:N - In memory-tiering and ballooning deployments the offline/migration pass runs automatically without any operator action, and the anomaly-triggered callers (`bad_page()`, `print_bad_pte()`, `filemap_unaccount_folio()`) require no victim involvement at all. The attacker\u0027s own pinning and dentry churn supply everything needed.\nS:U - The wild read and the resulting oops occur entirely within the kernel\u0027s own security authority, with no crossing of a VM, IOMMU, or sandbox boundary. This is a standard in-kernel memory-safety defect.\nC:H - `dentry_name()` reads an unbounded NUL-terminated run of kernel memory from a stale pointer and `pr_warn()` copies those bytes into the kernel ring buffer, which is world-readable by default (`kernel.dmesg_restrict=0`). Because the pointer is loaded from a freed `external_name`/dentry slot that an attacker can reclaim with sprayed data, the wild read can be steered toward a chosen kernel address, yielding an arbitrary-read-to-dmesg primitive rather than a bounded leak.\nI:N - `dump_mapping()` only loads from the stale pointer and formats the result; there is no out-of-bounds write, and `vsnprintf()`\u0027s `buf \u003c end` guard prevents the oversized string from overflowing the printk buffer. No kernel state is modified by the defect.\nA:H - The documented result is an unhandled supervisor page fault (\"BUG: unable to handle page fault for address: 0000000000001000\") at `dentry_name+0x1f4`, i.e. a kernel oops. It fires from inside `vprintk_store()` while the memory-hotplug path holds `mem_hotplug_lock`, so it can wedge printk and the hotplug machinery system-wide, and becomes a full panic under `panic_on_oops`."

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.
