Vulnerability from fkie_nvd - Published: 2025-06-18 11:15 - Updated: 2026-08-15 13:17

Severity

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

Summary

In the Linux kernel, the following vulnerability has been resolved: HID: nintendo: fix rumble worker null pointer deref We can dereference a null pointer trying to queue work to a destroyed workqueue. If the device is disconnected, nintendo_hid_remove is called, in which the rumble_queue is destroyed. Avoid using that queue to defer rumble work once the controller state is set to JOYCON_CTLR_STATE_REMOVED. This eliminates the null pointer dereference.

Attacker-influenced races are Low complexity under the required guidance.\nPR:N - An adjacent Bluetooth HID peer needs no local account or capability on the victim. Driver remove and report handling run from the Bluetooth/HID stack, not from attacker-held OS privileges.\nUI:N - Once a controller is paired or otherwise connected in normal gaming/handheld use, disconnect and rumble scheduling proceed without further victim action. Pairing is treated as an environmental precondition, not required interaction.\nS:U - The fault is in host-kernel HID/workqueue handling and stays within the same kernel security authority, with no VM, IOMMU, or sandbox boundary crossed.\nC:H - `nintendo_hid_remove()` calls `destroy_workqueue(ctlr-\u003erumble_queue)` without clearing the pointer, then `joycon_parse_report()`/`joycon_set_rumble()` can `queue_work()` on the freed workqueue. That dangling-pointer UAF is scored as high confidentiality impact.\nI:H - Queuing work through a destroyed `workqueue_struct` is kernel heap use-after-free of workqueue state, which is defensibly exploitable for memory corruption or control-flow integrity compromise under the required UAF guidance.\nA:H - Use of the destroyed rumble workqueue causes a kernel oops/panic-class crash (as described in the fix), so availability impact is High."

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.
