      <title>CVE-2026-97982 — net: ethernet: cortina: Fix budget accounting</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-97982</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: ethernet: cortina: Fix budget accounting&lt;/p&gt;
&lt;p&gt;The gmac_rx() function returns the remaining NAPI budget, but its
caller treats the return value as the number of packets received. An
idle poll therefore reports a full budget and remains scheduled.&lt;/p&gt;
&lt;p&gt;Return the number of received packets instead. Preserve the existing
free queue refill accounting by adding that count directly; continuing
to subtract it from the budget would invert the refill behavior.&lt;/p&gt;</description>
