NVD Description

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

tracing/histograms: Verify event_call identity when updating synth_event refcount

In event_hist_trigger_parse() and hist_unreg_all(), the histogram registration and unregistration paths look up find_synth_event() using trace_event_name(file->event_call) and adjust se->ref if a match is found.

Because find_synth_event() only compares the event basename, registering or removing a histogram on a non-synthetic trace event whose basename matches a synthetic event erroneously modifies the synthetic event's reference count. If a histogram is registered on the non-synthetic event before the synthetic event is created and removed afterwards, se->ref is decremented without a matching increment, allowing the synthetic event to be freed while an active histogram action still holds a pointer to it.

Introduce find_synth_event_call() to verify that &se->call matches file->event_call before adjusting se->ref.
