Description

A flaw was found in the Linux kernel's USB Human Interface Device (HID) gadget driver (`f_hid`). When a USB gadget is unbound and then rebound while file descriptors are still actively using its wait queues, the driver can re-initialize these queues while they still contain items. This can lead to list corruption, potentially causing system instability or a denial of service.
