In the Linux kernel, the following vulnerability has been resolved: net/sched: act_gate: snapshot parameters with RCU on replace The gate action can be replaced while the hrtimer callback or dump path is walking the schedule list.

When REPLACE omits the entry list, preserve the existing schedule so the effective state is unchanged.
