      <title>CVE-2026-74437 — media: uvcvideo: Fix deadlock if uvc_status_stop is called from async_ctrl.work</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-74437</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;media: uvcvideo: Fix deadlock if uvc_status_stop is called from async_ctrl.work&lt;/p&gt;
&lt;p&gt;If a UVC camera has an asynchronous control, uvc_status_stop may be
called from async_ctrl.work:&lt;/p&gt;
&lt;p&gt;uvc_ctrl_status_event_work()
    uvc_ctrl_status_event()
        uvc_ctrl_clear_handle()
	    uvc_pm_put()
	        uvc_status_put()
		    uvc_status_stop()
		        cancel_work_sync()&lt;/p&gt;
&lt;p&gt;This will cause a deadlock, since cancel_work_sync will wait for
uvc_ctrl_status_event_work to complete before returning.&lt;/p&gt;
&lt;p&gt;Fix this by returning early from uvc_status_stop if we are currently in
the work function. flush_status now remains false until uvc_status_start
is called again, ensuring that uvc_ctrl_status_event_work won&amp;#39;t resubmit
the URB.&lt;/p&gt;</description>
