      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ntracing: Check return value of __register_event() in trace_module_add_events()\n\ntrace_module_add_events() ignores the return value of __register_event()\nand unconditionally calls __add_event_to_tracers() for each event.\n\nIf __register_event() fails (for example, if event_init() fails), the\ntrace_event_call is not added to ftrace_events list, but\n__add_event_to_tracers() still creates a trace_event_file pointing to it.\nIf module loading subsequently fails and module memory is freed, tracing\nstate retains a stale trace_event_call pointer in trace_event_file,\nleading to a use-after-free when tracefs or tracing subsystem operations\nare later executed.\n\nFix this by checking the return value of __register_event() and only\ncalling __add_event_to_tracers() if event registration succeeded.",
