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
