Vulnerability from github – Published: 2025-06-18 12:30 – Updated: 2025-11-13 21:31

Details

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.

Severity

5.5 (Medium)

Bluetooth adjacency is the highest reasonable vector versus USB-physical.\nAC:L - The bug is a remove-versus-`queue_work` race on `rumble_queue`, and the Bluetooth peer controls disconnect timing and can retry while rumble is active. 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."
