CVE-2026-23014

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