5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Details

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
