NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt package and not the kernel-rt package as distributed by Rocky-Linux. See How to fix? for Rocky-Linux:10 relevant fixed versions and status.

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.
