CVE-2025-38087 – Linux Kernel Taprio Use-After-Free Vulnerability

CVE ID : CVE-2025-38087

Published : June 30, 2025, 8:15 a.m. | 43 minutes ago

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.

Severity: 0.0 | NA
