Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-23245)
