  "title": "perf/core: Allow list_del during perf_event_overflow()",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  perf/core: Allow list_del during perf_event_overflow()  A PMU might use perf_sched_cb_inc() and perf_sched_cb_dec() interface to get the PMU call back function pmu::sched_task invoked at schedule in and schedule out. This is achieved by walking along the list anchored by sched_cb_list.  The following scenario might lead to a list corruption.     perf_pmu_sched_task()       for_each_list_entry(..., \u0026sched_cb_list)       \u002B--\u003E __perf_pmu_sched_task()            \u002B--\u003E event-\u003Epmu-\u003Esched_task())                 \u002B--\u003E PMU_push_sample()                      \u002B--\u003E perf_event_overflow()                           \u002B--\u003E __perf_event_overflow()                                \u002B--\u003E pmu-\u003Estop()                                     \u002B--\u003E perf_sched_cb_dec()                                          remove entry from sched_cb_list                                          while list node in use.  This happens when ioctl(fd, PERF_EVENT_IOC_REFRESH, xxx) has been invoked and perf_event::event_limit hits zero.  Prevent the list corruption and convert for_each_list_entry() to for_each_list_entry_safe().",
