CVE-2024-50127 Description

In the Linux kernel, the following vulnerability has been resolved: net: sched: fix use-after-free in taprio_change() 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.
