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.
