CVE-2025-38087 Details
Description
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.
A use-after-free vulnerability has been identified in the Linux kernel's taprio scheduling feature. The issue arises in the taprio_dev_notifier function, which is not safeguarded by an RCU read-side critical section. This lack of protection can create a race condition with the advance_sched function, leading to memory management errors. The vulnerability has been addressed by adding an RCU read lock in the taprio_dev_notifier function, ensuring proper synchronization and preventing the use-after-free condition.
