Vulnerability from fkie_nvd - Published: 2024-12-27 14:15 - Updated: 2026-06-17 08:08

Severity

7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Summary

In the Linux kernel, the following vulnerability has been resolved: ALSA: 6fire: Release resources at card release The current 6fire code tries to release the resources right after the call of usb6fire_chip_abort(). But at this moment, the card object might be still in use (as we're calling snd_card_free_when_closed()). For avoid potential UAFs, move the release of resources to the card's private_free instead of the manual call of usb6fire_chip_destroy() at the USB disconnect callback.

This matches the AV:L scoring used for the sibling ALSA-USB disconnect CVEs in the same patch series (CVE-2024-56531).\nAC:L - There is no race to win: the free happens at teardown and the use happens at a moment the attacker chooses (`close()`), so the reclaim window is unbounded and the attacker can spray the corresponding kmalloc caches at leisure. The object sizes are stable and deterministic, making reliable reclaim straightforward.\nPR:L - The attacker only needs an ordinary unprivileged local account with access to the sound devices \u2014 granted by default to the active seat via systemd-logind uaccess ACLs or `audio` group membership. No capability, root, or namespace privilege is required.\nUI:N - The attacker performs every step themselves \u2014 opening the PCM/MIDI device, causing the card teardown, spraying the heap, and closing the fd. No action by a separate victim user is needed for the use-after-free to fire.\nS:U - The corruption is confined to kernel heap memory managed by the same kernel security authority; there is no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - The freed `pcm_runtime`/`midi_runtime`/`comm_runtime`/`control_runtime` objects are reclaimable by attacker-controlled or victim-owned allocations, and the driver then reads chained pointers (`rt-\u003echip-\u003econtrol`, `rt-\u003echip-\u003edev`, `sub-\u003einstance-\u003eruntime`) out of them, giving an attacker-steerable read primitive into arbitrary kernel memory.\nI:H - `usb6fire_pcm_close()` writes into the freed object (`sub-\u003einstance`, `sub-\u003eactive`, `rt-\u003estream_state`, `rt-\u003erate`) and `usb6fire_pcm_stream_stop()` performs an indirect call via `ctrl_rt-\u003eupdate_streaming()` \u2014 a function pointer read from reclaimed memory; the rawmidi path additionally calls `usb_submit_urb()` on a freed embedded `struct urb`, yielding a controlled `urb-\u003ecomplete` callback and full control-flow hijack potential.\nA:H - Even without controlled reclaim, dereferencing and locking the freed structures (`mutex_lock(\u0026rt-\u003estream_mutex)`, `spin_lock_irqsave(\u0026rt-\u003eout_lock)`) on poisoned or reused slab memory reliably produces an oops, lock corruption, or kernel panic, taking the system down."

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.
