      <title>CVE-2026-23313 — i40e: Fix preempt count leak in napi poll tracepoint</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-23313</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;i40e: Fix preempt count leak in napi poll tracepoint&lt;/p&gt;
&lt;p&gt;Using get_cpu() in the tracepoint assignment causes an obvious preempt
count leak because nothing invokes put_cpu() to undo it:&lt;/p&gt;
&lt;p&gt;softirq: huh, entered softirq 3 NET_RX with preempt_count 00000100, exited with 00000101?&lt;/p&gt;
&lt;p&gt;This clearly has seen a lot of testing in the last 3+ years...&lt;/p&gt;
&lt;p&gt;Use smp_processor_id() instead.&lt;/p&gt;</description>
