Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
mei: bus: access mei_device under device_lock on cleanup<br />
<br />
Fix couple of problems in mei_cl_bus_dev_release():<br />
<br />
mei_cl_flush_queues() is running without lock.<br />
bus->file_list access after mei_dev_bus_put(bus) can become a<br />
use-after-free if this was the last reference to bus.<br />
<br />
Protect queues cleanup and WARN traversal by device lock there<br />
to avoid the concurrent access problems.<br />
Move WARN traversal before mei_dev_bus_put(bus).<br />
<br />
This file uses bus variable name for mei_device, adjust<br />
code of mei_cl_bus_dev_release() to use bus variable too.
