In the Linux kernel, the following vulnerability has been resolved:
net/sched: fix use-after-free in taprio_dev_notifier
Since taprio’s taprio_dev_notifier() isn’t protected by an RCU read-side critical section, a race with advance_sched() can lead to a use-after-free.
Adding rcu_read_lock() inside taprio_dev_notifier() prevents this.
