      "value": "A use-after-free vulnerability in the Linux Kernel Performance Events system can be exploited to achieve local privilege escalation.\n\nThe perf_group_detach function did not check the event's siblings' attach_state before calling add_event_to_groups(), but\u00a0remove_on_exec made it possible to call list_del_event() on before detaching from their group, making it possible to use a dangling pointer causing a use-after-free vulnerability.\n\nWe recommend upgrading past commit fd0815f632c24878e325821943edccc7fde947a2.\n\n"
