Summary
In the Linux kernel, the following vulnerability has been resolved:
blk-mq: make sure active queue usage is held for bio_integrity_prep()
blk_integrity_unregister() can come if queue usage counter isn't held
for one bio with integrity prepared, so this request may be completed with
calling profile->complete_fn, then kernel panic.
Another constraint is that bio_integrity_prep() needs to be called
before bio merge.
Fix the issue by:
- call bio_integrity_prep() with one queue usage counter grabbed reliably
- call bio_integrity_prep() before bio merge
