Doc Text:	A flaw was found in the Linux kernel's logitech-hidpp driver. During the initialization of a force-feedback device, if certain memory allocations fail, the driver does not properly clean up previously allocated resources. This improper resource management could lead to a resource leak, potentially impacting system stability.	Story Points:	---

Description OSIDB Bzimport 2026-09-17 19:02:56 UTC

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

HID: logitech-hidpp: Fix FF device cleanup on init failure

hidpp_ff_init() creates the input force-feedback device with
input_ff_create(), then allocates the HID++ FF private data,
effect ID array, and workqueue.

If any of those allocations fail after input_ff_create() succeeds,
the function returns an error without destroying the FF device.
Add an unwind path that frees the private allocations made by
hidpp_ff_init() and calls input_ff_destroy() for failures after
input_ff_create() succeeds.
