AI-suggested

A fix is available and has been applied in the Linux kernel source. Users should update to a kernel version that includes the fix identified by the commits d723bc1fe2e72b9252234e94c11af644ec477bf7 and others listed. No additional mitigation is required beyond applying the official patch.

Description

A vulnerability in the Linux kernel's Nintendo HID driver was fixed by changing when the input device is registered. Previously, the device was registered before all capabilities, including force-feedback, were set, which could cause a NULL pointer dereference and incomplete device information exposure to userspace.
