  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nHID: roccat: fix use-after-free in roccat_report_event\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.\nProtect the readers list traversal with the readers_lock mutex.", "A flaw was found in the Linux kernel's roccat Human Interface Device (HID) driver. This vulnerability, a use-after-free, arises from a synchronization issue where the `roccat_report_event()` function accesses a list of readers without adequate locking. A local attacker could exploit this to cause a system crash (denial of service) or potentially execute arbitrary code, compromising system integrity." ],
