CVE-2025-38087: Linux Kernel

High severity, CVSS 7.8. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: from 6.3, before 6.6.95 (fixed in 6.6.95); from 6.7, before 6.12.35 (fixed in 6.12.35); from 6.13, before 6.15.4 (fixed in 6.15.4); version 6.16 only
