      <title>CVE-2024-40977 — wifi: mt76: mt7921s: fix potential hung tasks during chip recovery</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2024-40977</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: mt7921s: fix potential hung tasks during chip recovery&lt;/p&gt;
&lt;p&gt;During chip recovery (e.g. chip reset), there is a possible situation that
kernel worker reset_work is holding the lock and waiting for kernel thread
stat_worker to be parked, while stat_worker is waiting for the release of
the same lock.
It causes a deadlock resulting in the dumping of hung tasks messages and
possible rebooting of the device.&lt;/p&gt;
&lt;p&gt;This patch prevents the execution of stat_worker during the chip recovery.&lt;/p&gt;</description>
