      <title>CVE-2024-47714 — wifi: mt76: mt7996: use hweight16 to get correct tx antenna</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2024-47714</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: use hweight16 to get correct tx antenna&lt;/p&gt;
&lt;p&gt;The chainmask is u16 so using hweight8 cannot get correct tx_ant.
Without this patch, the tx_ant of band 2 would be -1 and lead to the
following issue:
BUG: KASAN: stack-out-of-bounds in mt7996_mcu_add_sta+0x12e0/0x16e0 [mt7996e]&lt;/p&gt;</description>
