Full technical detail▾

Overview

In the Linux kernel, the following vulnerability has been resolved:

block: don't use submit_bio_noacct_nocheck in blk_zone_wplug_bio_work

Bios queued up in the zone write plug have already gone through all all preparation in the submit_bio path, including the freeze protection.

Submitting them through submit_bio_noacct_nocheck duplicates the work and can can cause deadlocks when freezing a queue with pending bio write plugs.

Go straight to ->submit_bio or blk_mq_submit_bio to bypass the superfluous extra freeze protection and checks.
