      <title>CVE-2026-90370 — wifi: mt76: mt7996: bound TLV walk in mt7996_mcu_get_chip_config</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-90370</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: mt76: mt7996: bound TLV walk in mt7996_mcu_get_chip_config&lt;/p&gt;
&lt;p&gt;The response TLV loop advanced by tlv-&amp;gt;len without a minimum, so a
theoretical firmware response containing a zero-length TLV could spin
forever, hanging the CPU during device probe.
The u32 payload was also read without bounds checking.
Reject a short fixed field, stop on a TLV whose length underruns the
header or overruns the skb.&lt;/p&gt;</description>
