Description
A use-after-free vulnerability in the Linux kernel's HID winwing driver related to force feedback teardown has been fixed. The issue arises from improper freeing of driver private data, leading to double free and slab corruption during device teardown or system suspend. The fix involves changing the force-feedback context handling to prevent invalid frees.
