CVE-2026-90014

In the Linux kernel, the following vulnerability has been resolved:

tracing: Have show_event_filters/triggers files take trace array ref

The newly added files show_event_filters and show_event_triggers that show

all filters or triggers that are set within the trace array do not take a

reference for the trace array it is showing. Without taking a reference,

the trace_array may be freed via "rmdir" while a task is reading one of

theses files. Those files iterate all the events within an instance

(trace_array) and nothing prevents that instance from being freed while

its data is being read. This causes a use-after-free crash.

Have the open of both those files take the trace_array reference via the

trace_array_get() that prevents the trace_array from being freed while the

files are opened.
