Dmitry Antipov e10f4d31cc net: sched: fix use-after-free in taprio_change() ... [ Upstream commit f504465970aebb2467da548f7c1efbbf36d0f44b ] In 'taprio_change()', 'admin' pointer may become dangling due to sched switch / removal caused by 'advance_sched()', and critical section protected by 'q->current_entry_lock' is too small to prevent from such a scenario (which causes use-after-free detected by KASAN). Fix this by prefer 'rcu_replace_pointer()' over 'rcu_assign_pointer()' to update 'admin' immediately before an attempt to schedule freeing.
