CVE-2026-23245

net/sched: act_gate: snapshot parameters with RCU on replace

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.

Convert the parameters to an RCU-protected snapshot and swap updates under
tcf_lock, freeing the previous snapshot via call_rcu(). When REPLACE omits
the entry list, preserve the existing schedule so the effective state is
unchanged.
