In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
tracing: Have show_event_filters\/triggers files take trace array ref<\/p>\n
The newly added files show_event_filters and show_event_triggers that show
\nall filters or triggers that are set within the trace array do not take a
\nreference for the trace array it is showing. Without taking a reference,
\nthe trace_array may be freed via “rmdir” while a task is reading one of
\ntheses files. Those files iterate all the events within an instance
\n(trace_array) and nothing prevents that instance from being freed while
\nits data is being read. This causes a use-after-free crash.<\/p>\n
Have the open of both those files take the trace_array reference via the
\ntrace_array_get() that prevents the trace_array from being freed while the
\nfiles are opened.<\/p>\n","protected":false},"excerpt":{"rendered":"
