      <title>CVE-2026-74340 — wifi: wcn36xx: fix OOB read from firmware count in PRINT_REG_INFO indication</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-74340</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;wifi: wcn36xx: fix OOB read from firmware count in PRINT_REG_INFO indication&lt;/p&gt;
&lt;p&gt;The firmware-controlled rsp-&amp;gt;count field is used as the loop bound for
indexing into the flexible rsp-&amp;gt;regs[] array without validation against
the message length. A count exceeding the actual data causes out-of-
bounds reads from the heap-allocated message buffer.&lt;/p&gt;
&lt;p&gt;Add a check that count fits within the received message.&lt;/p&gt;</description>
