Overview

CVE-2022-49974 is a high-severity vulnerability. It was published on June 18, 2025 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
