    "lastseen": "",
    "description": "In the Linux kernel, the following vulnerability has been resolved:\n\nHID: roccat: fix use-after-free in roccat_report_event\n\nroccat_report_event() iterates over the device->readers list without\nholding the readers_lock. This allows a concurrent roccat_release() to\nremove and free a reader while it's still being accessed, leading to a\nuse-after-free.\n\nProtect the readers list traversal with the readers_lock mutex.",
