  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nHID: roccat: free buffered reports when destroying device\n\nroccat_report_event() duplicates each report with kmemdup() and stores\nthe allocation in a circular-buffer slot. 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.",
