Official 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.
