In the Linux kernel, the following vulnerability has been resolved: HID: roccat: free buffered reports when destroying device roccat_report_event() duplicates each report with kmemdup() and stores the allocation in a circular-buffer slot. The allocation is released only when that slot is reused. The device destruction paths free struct roccat_device without releasing reports still stored in cbuf[]. This makes those allocations unreachable and leaks up to ROCCAT_CBUF_SIZE report buffers per device. Add a small destructor that frees every buffered report before freeing the device, and use it in both paths that can destroy a registered device.
