Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> block: don&amp;#39;t use submit_bio_noacct_nocheck in blk_zone_wplug_bio_work<br /> <br /> Bios queued up in the zone write plug have already gone through all all<br /> preparation in the submit_bio path, including the freeze protection.<br /> <br /> Submitting them through submit_bio_noacct_nocheck duplicates the work<br /> and can can cause deadlocks when freezing a queue with pending bio<br /> write plugs.<br /> <br /> Go straight to -&gt;submit_bio or blk_mq_submit_bio to bypass the<br /> superfluous extra freeze protection and checks.
