Detailsinfo

A vulnerability was found in Linux Kernel up to 5.19.6. It has been classified as critical. Affected is the function nintendo_hid_remove of the component HID. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on availability. CVE summarizes:

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.

The advisory is shared for download at git.kernel.org. This vulnerability is traded as CVE-2022-49974 since 06/18/2025. There are known technical details, but no exploit is available.

Upgrading to version 5.19.7 eliminates this vulnerability. Applying the patch 7c6e6c334154be16740b44dcd7638fb510b9bd91/1ff89e06c2e5fab30274e4b02360d4241d6e605e is able to eliminate this problem.
