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.
