Doc Text:	A flaw was found in the Linux kernel's Human Interface Device (HID) PlayStation driver. The `ps_gamepad_create()` function does not verify the return value of `input_ff_create_memless()`. This missing check can lead to incorrect behavior or potential system crashes when Force Feedback (FF) effects are activated. This vulnerability could result in a Denial of Service (DoS) for an affected system.	Story Points:	---

Description OSIDB Bzimport 2026-05-27 15:08:31 UTC

In the Linux kernel, the following vulnerability has been resolved:

HID: playstation: Add missing check for input_ff_create_memless

The ps_gamepad_create() function calls input_ff_create_memless()
without verifying its return value,  which can lead to incorrect
behavior or potential crashes when FF effects are triggered.

Add a check for the return value of input_ff_create_memless().
