CVE-2026-23245

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net/sched: act_gate: snapshot parameters with RCU on replace<br /> <br /> The gate action can be replaced while the hrtimer callback or dump path is<br /> walking the schedule list.<br /> <br /> Convert the parameters to an RCU-protected snapshot and swap updates under<br /> tcf_lock, freeing the previous snapshot via call_rcu(). When REPLACE omits<br /> the entry list, preserve the existing schedule so the effective state is<br /> unchanged.
