The allocation is released only\nwhen that slot is reused.\n\nThe device destruction paths free struct roccat_device without releasing\nreports still stored in cbuf[]. This makes those allocations unreachable\nand leaks up to ROCCAT_CBUF_SIZE report buffers per device.\n\nAdd a small destructor that frees every buffered report before freeing the\ndevice, and use it in both paths that can destroy a registered device.","state":0,"publishedAt":"2026-09-11T19:45:23.479+00:00","modifiedAt":"2026-10-19T08:49:59.521+00:00","affected":[{"ecosystem":"Vendor
