Vulnerability Details CVE-2026-23014
In the Linux kernel, the following vulnerability has been resolved:
perf: Ensure swevent hrtimer is properly destroyed
With the change to hrtimer_try_to_cancel() in
perf_swevent_cancel_hrtimer() it appears possible for the hrtimer to
still be active by the time the event gets freed.
Make sure the event does a full hrtimer_cancel() on the free path by
installing a perf_event::destroy handler.
