Description

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.
