      <title>CVE-2025-38087 — net/sched: fix use-after-free in taprio_dev_notifier</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2025-38087</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Linux&lt;/p&gt;
&lt;p&gt;In the Linux kernel, the following vulnerability has been resolved:&lt;/p&gt;
&lt;p&gt;net/sched: fix use-after-free in taprio_dev_notifier&lt;/p&gt;
&lt;p&gt;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.&lt;/p&gt;
&lt;p&gt;Adding rcu_read_lock() inside taprio_dev_notifier() prevents this.&lt;/p&gt;</description>
